RESUMO
BACKGROUND AND OBJECTIVES: Patient-clinician communication and shared decision-making face challenges in the perioperative period. Chatbots have emerged as valuable support tools in perioperative care. A simultaneous and complete comparison of overall benefits and harm of chatbot application is conducted. MATERIALS: MEDLINE, EMBASE and the Cochrane Library were systematically searched for studies published before May 2023 on the benefits and harm of chatbots used in the perioperative period. The major outcomes assessed were patient satisfaction and knowledge acquisition. Untransformed proportion (PR) with a 95% CI was used for the analysis of continuous data. Risk of bias was assessed using the Cochrane Risk of Bias assessment tool version 2 and the Methodological Index for Non-Randomised Studies. RESULTS: Eight trials comprising 1073 adults from four countries were included. Most interventions (n = 5, 62.5%) targeted perioperative care in orthopaedics. Most interventions use rule-based chatbots (n = 7, 87.5%). This meta-analysis found that the majority of the participants were satisfied with the use of chatbots (mean proportion=0.73; 95% CI: 0.62 to 0.85), and agreed that they gained knowledge in their perioperative period (mean proportion=0.80; 95% CI: 0.74 to 0.87). CONCLUSION: This review demonstrates that perioperative chatbots are well received by the majority of patients with no reports of harm to-date. Chatbots may be considered as an aid in perioperative communication between patients and clinicians and shared decision-making. These findings may be used to guide the healthcare providers, policymakers and researchers for enhancing perioperative care.

BACKGROUND: Hepatocellular carcinoma (HCC) remains a major cause of cancer-related mortality worldwide, with treatment options including radiofrequency ablation (RFA) and surgical resection. This study evaluates the evolving guidelines for these treatments to identify the current consensus and divergences. METHOD: We conducted a systematic review following PRISMA 2020 guidelines of documents from 2017-2024 by major liver societies. The AGREE-II framework assessed guideline quality. This study is registered with PROSPERO (CRDXXXX). RESULTS: We analyzed 23 guidelines and noted significant shifts in treatment recommendations over recent updates. This analysis reveals an increasing endorsement of RFA for certain patient groups and sustained strong support for surgical resection based on robust evidence levels. All demonstrated high quality, with the 2023 Japan Guidelines receiving the highest AGREE-II score. A significant finding was the low level of stakeholder involvement in the development of guidelines. CONCLUSION: The study highlights the dynamic nature of clinical guidelines for early-stage HCC, underscoring the need for ongoing updates and direct, high-quality comparative studies. The evolving recommendations for RFA, especially its role in managing small, localized tumors, reflect its emerging importance in the treatment paradigm.
RESUMO
Background: Necrotizing soft-tissue infection (NSTI) is a rare and serious disease with high morbidity and mortality. Standard therapeutic concepts have included urgent surgical intervention, broad-spectrum antibiotic treatment, and intensive care. Hyperbaric oxygen therapy (HBOT) is used as adjuvant therapy in some centers, but its benefits remain controversial. Methods: A retrospective analysis was conducted in which 98 patients with a clinical diagnosis of NSTI were treated with standard treatments plus HBOT. The clinical outcomes were wound healing, performance status, hospital length, complication rate, recurrence rate, morbidity (amputation rate), and mortality. Primary or secondary outcomes were compared between the time interval of HBOT and the clinical outcomes. Results: The average times from diagnosis of NSTI to initial HBO treatment and from initial surgery to initial HBO treatment were both significantly longer in dead patients than in surviving patients (P = 0.031; P = 0.020). These two time intervals were both significantly longer in amputated patients than in preserved patients (P = 0.031; P = 0.037). Conclusions: Using combined treatment with early surgical debridement combined with HBOT, it is possible to reduce hospital stay, intensive care unit stay, number of debridements, improve complete wound healing rate, and lower amputation and mortality rates among patients with NSTI. The early onset of HBOT soon after diagnosis, especially during critical conditions, is proved to be associated with higher survival and preservation rates.
RESUMO
BACKGROUND: Liver resection (LR) and radiofrequency ablation (RFA) are the most commonly used treatment modalities for early-stage hepatocellular carcinoma (ES-HCC). The comparative efficacy of LR and RFA in ES-HCC remains debated. We conducted a meta-analysis based on randomized trials to compare the outcomes of LR and RFA. METHODS: We searched PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing RFA and LR interventions for the treatment of ES-HCC. The primary outcomes were overall survival (OS) and disease-free survival (DFS). We used meta-regression to determine the source of heterogeneity and conducted a trial sequential analysis to examine whether the outcome was statistically reliable. RESULTS: Our meta-analysis included nine RCTs with a total of 1,516 HCC patients. Compared with patients receiving RFA, those receiving LR did not have significantly different 2-year OS (HR=1.28, 95% CI: 0.73-2.23) and 5-year OS (HR=1.49, 95% CI: 0.99-2.24). However, patients receiving LR showed a favorable trend in 2-year DFS (HR=1.40, 95% CI: 1.16-1.69) and 5-year DFS (HR=1.37; 95% CI: 1.05-1.77), although these results are not conclusive due to underpowered significance. The heterogeneity was low, and the outcomes were statistically reliable. DISCUSSION: Meta-analysis suggests that while LR shows a favorable trend in DFS compared to RFA for ES-HCC, the present evidence does not thoroughly support recommending LR over RFA. The inconclusive nature of these findings highlights the need for further large-scale RCTs to establish definitive comparative efficacy.
RESUMO
BACKGROUND: Oral mucositis significantly compromises the quality of life for patients undergoing cancer therapies. This study aimed to evaluate the effectiveness of natural products in either preventing or alleviating oral mucositis resulting from cancer treatments. METHODS: A systematic review and network meta-analysis were conducted, sourcing data from the Cochrane Library, PubMed, Embase, Airiti Library, and Wan Fang Data Knowledge Service Platform until August 2023. The study was registered in PROSPERO (CRD42021285433). Confidence in Network Meta-Analysis (CINeMA) and R software 4.1.3 were used for analysis. RESULTS: From 1556 identified articles, 36 randomized controlled trials (RCTs) were analyzed, involving 2083 patients. Honey, notably, was found to significantly reduce the overall incidence of oral mucositis compared to standard care, with a relative risk (RR) of 0.80 (95% CI: 0.67-0.96). It was particularly effective against moderate-to-severe oral mucositis (grade ≥ 2), reducing incidence with RR of 0.48 (95% CI: 0.30-0.75) versus placebo and 0.56 (95% CI: 0.34-0.93) against standard care. Other natural products, including propolis, chamomile, and P. major L., also demonstrated significant efficacy in reducing the incidence of oral mucositis. Regarding pain relief, honey, and P. major L. emerged as effective, significantly reducing pain severity with a mean difference (MD) of -2.96 (95% CI: -3.80 to -1.94) compared to placebo. CONCUSSION: This network meta-analysis supports the use of honey, propolis, chamomile, and P. major L. as effective natural products in the prevention and treatment of oral mucositis among cancer patients. Specifically, honey is highlighted for its significant impact on reducing both the overall incidence and the severity of moderate-to-severe oral mucositis. By leveraging their anti-inflammatory and antioxidant properties, integrating these natural products into the standard care regimen could markedly improve the well-being of individuals undergoing cancer therapy.

BACKGROUND: Striae distensae (SD) are cutaneous lesions that are caused by hormones or mechanical stress leading to rapid expansion of skin. Therefore, SD are now a cosmetic concern. However, improving SD is notoriously difficult. Among different treatments, energy-based devices (EBDs) are much more effective and controllable. OBJECTIVE: The aim of this review was to determine the most effective type of EBD for improving the appearance of striae. MATERIALS AND METHODS: The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The population comprised patients suffering from striae. Different types of EBDs used to improve striae were compared. The primary outcome of the reduction in the width of striae was evaluated. A random-effects model was performed. The means and standard deviations were extracted. RESULTS: Eighteen randomized controlled trials were included. The network meta-analysis revealed that after a comparison among the 4 types of EBDs, no significant differences were observed in the reduction of striae width. CONCLUSION: Radiofrequency, ablative lasers, nonablative lasers, and intense pulsed light are all effective treatments for reducing the striae width. None of them was superior to the others. However, radiofrequency and ablative lasers may have the highest chance of improving the appearance of striae.
RESUMO
OBJECTIVE: Patients often experience pain and psychological distress when undergoing elective surgeries. Mindfulness-based interventions have been proposed as potential strategies to address these challenges. This meta-analysis aims to evaluate the efficacy of preoperative mindfulness-based interventions on several outcomes for patients undergoing elective surgery, including preoperative anxiety/depression, postoperative anxiety/depression, postoperative pain, and quality of life (QOL). METHODS: This meta-analysis encompassed randomized controlled trials published in the database PubMed, Cochrane, and Embase to August 2023. Mindfulness-based interventions were compared to control groups, who received treatment as usual (TAU). The RevMan software was employed to assess each outcome by using standardized mean difference based on patient-reported data. Subgroup analyses were further performed according to different categories of surgical types. RESULTS: Eight RCTs with a total of 685 patients were identified. This meta-analysis demonstrated significant difference in preoperative anxiety (SMD:-0.36, 95% CI: -0.62 to -0.11, p = .006) and postoperative pain immediately (SMD:-0.65,95% CI: -1.09 to -0.20, p = .004), 2-3 days (SMD:-0.40, 95% CI:-0.78 to -0.02, p = .04),at 14 days (SMD:-0.48,95% CI: -0.85 to -0.12, p = .009) and 28 days (SMD:-0.89,95% CI: -1.55 to -0.23, p = .008) postoperatively. However, there were no differences between postoperative anxiety, preoperative/postoperative depression, and QOL. CONCLUSION: Our findings suggest preoperative mindfulness-based interventions can effectively manage preoperative anxiety and postoperative pain in patients scheduled for elective surgery. Further research is warranted to explore the different timing and types of mindfulness-based intervention.

BACKGROUND: Nasolabial fold formation is increasingly becoming a cause of concern for many people. However, no network meta-analysis has compared the efficacy of different fillers in treating nasolabial folds. This network meta-analysis simultaneously compared the efficacy and safety of various fillers. METHODS: We included randomized controlled trials (RCTs) that used fillers to treat nasolabial folds. We extracted data of Wrinkle Severity Rating Scale (WSRS), Global Esthetic Improvement Scale (GAIS, investigator) scores, GAIS scores (self-reported) and adverse events. RESULTS: We included 13 RCTs. WSRS scores at 6 months were higher in patients receiving HA than those receiving poly (L-lactic acid) (mean difference [MD] 0.630, 95% confidence interval [CI] 0.275, 0.985) but significantly lower in patients receiving HA than in those receiving bovine collagen (MD - 0.580, 95% CI - 0.777, - 0.383) and porcine collagen (MD - 0.525, 95% CI - 0.790, - 0.260). Regarding adverse events, HA was significantly less likely to cause nodule formation compared with bovine collagen (RR 0.593, 95% CI 0.438, 0.803). CONCLUSION: HA is a safe filler for correcting nasolabial folds, and poly (L-lactic acid) showed potential in treating nasolabial folds.

RESUMO
Colorectal adenomas have the potential of malignant transformation if left untreated. Multiple randomized controlled trials have been performed to evaluate the efficacy of aspirin in preventing colorectal adenoma recurrence in a population with a history of colorectal adenoma but not colorectal cancer, however, the relationship between aspirin dose and colorectal adenoma recurrence remains unclear. We conducted pairwise meta-analysis, meta-regression, trial sequential analysis, and network meta-analysis of all eligible studies. The ROB 2.0 tool was used to assess the risk of bias in the studies. The confidence in network meta-analysis (CINeMA) approach was used to evaluate the confidence of the network meta-analysis results. The network meta-analysis included eight RCTs (nine reports), comprising four on aspirin (low or high dose) alone and four on aspirin combined with another medication, all compared with placebo. In the network meta-analysis, low-dose aspirin (LDA <300 mg per day) was more effective than high-dose aspirin (HDA ≥300 mg per day) and placebo, with risk ratios of 0.76 (95% CI: 0.58 to 0.99) and 0.7 (95% CI: 0.54 to 0.91), respectively. LDA was the optimal treatment relative to HDA and placebo (P-score = 0.99). In the trial sequential analysis, LDA was only more effective than placebo when the number of included participants exceeded the optimal information size; this was not the case for HDA. LDA has statistically significant efficacy for colorectal adenoma prevention, but compared with HDA, its efficacy remains uncertain. Further trials are therefore required.

BACKGROUND: Breast cancer has surpassed lung cancer to become the most frequently diagnosed cancer in women. There has been a dramatic increase in the use of breast reconstruction after mastectomy. However, struggle in making decisions regarding breast reconstruction has existed. Thus, decision aid (DA) is necessary to be conducted, and further studies are needed to promote better decision aid. This review discussed how DAs can be used to help women make decisions about breast reconstruction after mastectomy. Additionally, the review was the first to compare different DA formats to determine which one is most effective. METHODS: We searched for relevant studies published before October 2022 in PubMed and Embase using the medical subject headings "breast reconstruction" and "decision aid." Demographic data as well as decision, outcomes and instruments used for assessment were also collected. Risk of bias was measured by the Cochrane Risk-of-Bias 2 (RoB 2) tool. RESULTS: A network meta-analysis of 14 RCTs with a total of 1401 patients wereincluded. 90.9% participants presented usable results for evaluation of decisional conflict, and web-based DA (-0.3, 95% CI -0.56 to -0.05) showed significant improvement. 50.3% participants provided results of decisional regret, and no subgroups showed significant reduction. 60.3% participants contributed to results for knowledge, and web-based DA (0.61, 95% CI 0.01 to 1.21) showed the most positive effect. 44.5% participants were included for evaluation of satisfaction, and web-based DA (0.44, 95% CI 0.15 to 0.72) revealed significant increase. CONCLUSION: The review concluded that web-based decision aids are the favorable format of decision aid.
RESUMO
We would like to respond to the commentary with further understanding of the issue of potential statistical power in the analysis of our original finding. This further analysis has been planned to be carried out using the data from the wrinkle outcome because it has been contributed by the largest sample size with a dramatic effect size among all outcomes. Sequential analysis in this letter has been down with alpha 0.05 (type I error) and power of 0.80 (1-type II error) based on the O'Brien Fleming method. In addition to the common settings abovementioned, we chose a small effect size (SMD = 0.2) for avoiding underestimation in the optimal information size calculation and power analysis. The analysis was conducted using R via RStudio. The figure of sequential analysis shows that the cumulative effect of topical CM of stem cells on wrinkle outcome reaches statistical significance (z score of the end of blue line > 2), which is consistent with our original finding. Nevertheless, the information size of the outcome is insufficient (n = 118), which is lower than the required sample size (n = 1419). The observed power of the effects of topical CM of stem cells on the wrinkle outcome is only about 0.64, which is lower than the pre-defined or expected power of 0.80. Based on the fraction of information, although the observed z score of 3.232 for the cumulative effect surpasses 2, it does not surpass the monitoring boundary of 6.795 at the fraction (8.3%).Level of Evidence V This journal requires that authors assign a level of evidence to each article.

BACKGROUND: Alopecia is a common and distressing medical condition that has been related to psychiatric disorders. Stem cell-derived conditioned medium (CM), a novel therapy for hair regeneration, has shown effectiveness in several trials. METHODS: This meta-analysis aims to explore the effectiveness of stem cell-derived CM in improving hair growth for patients of alopecia. We prospectively registered this systematic review and meta-analysis in PROSPERO (CRD42023410249). Clinical trials that the enrolled participants suffering from alopecia applied stem cell-derived CM were included. We calculated the mean and standard deviation for the hair density and thickness. RESULTS: Ten clinical trials were included in our analysis. On the basis of eight clinical trials (n = 221), our pooled results indicate that stem cell-derived CM is effective in increasing hair density (mean difference [MD]: 14.93, confidence interval [95% CI]: 10.20-19.67, p < 0.0001) and thickness (MD: 18.67, 95% CI: 2.75-34.59, p < 0.0001) (µm) in patients with alopecia. Moreover, our findings suggest that longer treatment duration is associated with significantly greater improvement than shorter treatment duration (p = 0.02). Three of the included studies were randomized controlled trials (RCTs), and when we specifically analyzed these RCTs; statistical significance could also be observed in terms of hair density (MD: 9.23, 95% CI: 1.79-16.68, p < 0.00001). KEY MESSAGES: Stem cell-derived conditioned medium can effectively increase hair density and thickness for alopecia, and there is no difference between each method (topical application, microneedling, or injection).

The objective of this study was to examine the difference in sensory-motor impairments (i.e., balance, contracture, coordination, strength, spasticity, and sensation) between legs in children with hemiplegic cerebral palsy. An observational study measured both lower limbs of children with hemiplegic cerebral palsy over one session. Six sensory-motor impairments (balance, coordination, strength, spasticity, contracture, and proprioception) were measured. The between-leg differences were analyzed using the paired t-tests and presented as the mean differences (95% confidence interval (CI)). Twenty-four participants aged 10.3 years (standard deviation: 1.3) participated. The affected leg was less than the less-affected leg in terms of the strength of dorsiflexors (mean difference (MD) -2.8 Nm, 95% CI -4.2 to -1.4), plantarflexors (MD -2.6 Nm, 95% CI -4.1 to -1.0), knee extensors (MD -5.3 Nm, 95% CI -10.2 to -0.5) as well as range of ankle dorsiflexion (MD -8 deg, 95% CI -13 to -3), and balance (median difference -11.1, 95% CI -11.6 to -10.6). There was a trend toward a difference in terms of the strength of hip abductors (MD -2.6 Nm, 95% CI -5.3 to 0.1) and coordination (MD -0.20 taps/s, 95% CI -0.42 to 0.01). The legs were similar in terms of the strength of hip extensors (MD 0.3 Nm, 95% CI -4.7 to 5.3), proprioception (MD 1 deg, 95% CI 0 to 2), and spasticity (median difference 0, 95% CI 0 to 0). Examination of the difference in sensory-motor impairments between legs in children with hemiplegic cerebral palsy has given us some insights into the deficits in both legs. Not only was balance, strength, and coordination decreased compared with the less-affected leg but also the less-affected leg was markedly decreased compared with typically developing children. Therefore, an intervention aimed at increasing muscle strength and coordination in both legs might have a positive effect, particularly on more challenging physical activities. This may, in turn, lead to successful participation in mainstream sport and recreation.

Alpha-lipoic acid (ALA) was found to improve the symptoms in patients with diabetic sensorimotor peripheral neuropathy (DSPN) by reducing oxidative stress and ameliorating microcirculation. Our meta-analysis is aimed at evaluating the effects of oral-administered ALA versus a placebo in patients with DSPN and determining the optimal dosage for this treatment. We systematically reviewed randomized controlled trials (RCTs) in the PubMed, Embase, and Cochrane databases to determine the efficacy of oral ALA for patients with DSPN. The primary outcome was total symptoms' score (TSS), and secondary outcomes were the neurological disability score (NDS), neuropathy impaired score (NIS), NIS-lower limb (NIS-LL), vibration perception threshold (VPT), nerve conduction study (NCS) results, and global satisfaction. A subgroup analysis of the ALA dosage (600, 1200, and 1800 mg/day) was also conducted. Ten RCTs (1242 patients) were included. ALA treatment produced favorable results for TSS (a dose-related trend was observed), NDS, and the global satisfaction score. For VAS, VPT, NIS-LL, and NCS results, ALA did not produce favorable results. ALA treatment had favorable effects on DSPN by reducing sensory symptoms, and it resulted in a dose-dependent response relative to the placebo for TSS and the global satisfaction score. The use of ALA to prevent neurological symptoms should be further researched.

This systematic review and network meta-analysis investigated the clinical efficacy and safety of chemical agent injections in patients with varicose veins. PubMed, Embase, and Cochrane databases were searched for eligible studies where patients administered endovascular agents comprised an intervention group, and patients administered other interventions comprised the comparison group. The endovascular agents included foam and liquid form sclerotherapy or cyanoacrylate glue. The other interventions in this study included surgery, endovenous laser ablation (EVLA), radiofrequency ablation (RFA), and placebo. A network meta-analysis for treatment effectiveness was performed. In addition, we illustrated the P-score lines of success rate and complication rate sorted by the P-score. Our results showed that at all postprocedural time intervals, cyanoacrylate glue therapy exhibited a significantly higher success rate compared with foam and liquid sclerotherapy. According to the plot of P-score lines, cyanoacrylate glue had an overall tendency of higher success rate and lower complication rate compared with foam and liquid sclerotherapy. Comparing with the other invasive treatments, cyanoacrylate glue may be non-inferior and could be considered as an option for treating varicose veins. However, the clinical benefits and safety of endovascular agents for the treatment of varicose veins require further corroboration through randomized control trials.
RESUMO
This paper presents a systematic review and meta-analysis of 26 randomized controlled trials (RCTs) involving 1721 patients to assess the effects of hydrolyzed collagen (HC) supplementation on skin hydration and elasticity. The results showed that HC supplementation significantly improved skin hydration (test for overall effect: Z = 4.94, p < 0.00001) and elasticity (test for overall effect: Z = 4.49, p < 0.00001) compared to the placebo group. Subgroup analyses demonstrated that the effects of HC supplementation on skin hydration varied based on the source of collagen and the duration of supplementation. However, there were no significant differences in the effects of different sources (p = 0.21) of collagen or corresponding measurements (p = 0.06) on skin elasticity. The study also identified several biases in the included RCTs. Overall, the findings suggest that HC supplementation can have positive effects on skin health, but further large-scale randomized control trials are necessary to confirm these findings.

BACKGROUND: Laser hair removal is an increasingly prevalent trend of cosmetic procedures. The purpose of this study was to assess the effectiveness of hair reduction among several types of laser interventions. METHODS: The selected studies searched in PubMed and EMBASE were assessed for quality of evidence, and extracted data on absolute hair count and hair reduction rate. Qualitative data were synthesized using standardized mean difference (SMD) in frequentist network meta-analysis because various measurement units were used among selected studies. Inconsistency and small study effects were examined by design-by-treatment interaction model and comparison-adjusted funnel plot. RESULTS: A total of 13 randomized controlled trials (RCTs) (n = 652) were contributed to network meta-analysis. Pooled results revealed that diode laser showed significantly lower absolute hair count within three-month (SMD = -13.21, 95% confidence interval [CI]: -22.25 to -4.17) and around six months follow-up (SMD = -11.01, 95% CI: -18.24 to -3.77) as compared with those in control group, but no significant difference among laser interventions. All side effects observed were transient without leaving any permanent scars. CONCLUSION: Eliminating unwanted hair with lasers or intense pulsed light is safe and effective; however, which type of intervention is more beneficial in the long-term process should be studied with a longer follow-up time.

BACKGROUND: Rhinoplasty can cause tissue trauma and inflammatory responses. Edema and ecchymosis, especially on the face, accompanied by inflammation are common complications. The anti-inflammatory properties of steroids can reduce postoperative edema and ecchymosis. OBJECTIVE: This review aims to determine the most effective type of steroids for preventing complications related to rhinoplasty. METHODS: The study was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The population of comprised patients who underwent rhinoplasty or septorhinoplasty. Different types of steroids administrated intravenously during the perioperative period were compared. The primary outcome of postoperative edema and other outcomes were evaluated on postoperative day 1, 3, and 7. Random-effects model was performed. The means and standard deviations were extracted. RESULTS: Eighteen randomized controlled trials were included. The network meta-analysis revealed that dexamethasone and methylprednisolone significantly reduced edema on postoperative day 1 compared with placebo. No significant differences between the effects of any of two types of steroids were noted. CONCLUSION: At least one dose of intravenous steroid intervention is recommended during the perioperative period of rhinoplasty. However, in terms of reducing edema and ecchymosis, no significant differences were noted among dexamethasone, methylprednisolone, and betamethasone.

BACKGROUND: To test the effects of autologous fat grafting for reducing postmastectomy pain is important since post-operative pain bothers many patients with postmastectomy pain syndrome (PMPS), and one session autologous fat grafting for this condition is also investigated in some studies. Most of them show the positive effect on pain control, but the most recent randomized controlled trial (RCT) does not. The relatively small sample size with incomplete follow-up in the RCT might limit the certainty of evidence, and cases for the final analysis is lesser than expected numbers by sample size determination. Besides, there is no futility analysis to show the non-significant finding could be conclusive evidence. To check the conclusiveness of comparative evidence on this topic becomes a critical task for guiding clinicians and further studies in the future, therefore the purpose of this letter is to test whether evidence on fat grafting for alleviating pain amongst patients with PMPS is conclusive using sequential analysis. METHODS: This supplementary analysis used the data from the comparative evidence on fat grafting for PMPS based on the most recent RCT and previous systematic reviews. Complete data of pain score of two comparative studies from Italy were presented in a pooled report, therefore, this letter used data of pooled report for the Italy studies. Pooled mean difference (MD) in pain score between fat grafting and control groups was based on random-effects model. Quantitative synthesis consisted of cumulative meta-analysis and leave-one out sensitivity analysis due to heterogeneity from clinical setting across the included studies. Then, sequential analysis was further done with a conservative effect size (standardized mean difference = 0.2), type I error (α = 0.05), and power of 0.80 based on O'Brien Flemming method. All analyses were carried out using R version 4.1 via RStudio for Microsoft Windows. RESULTS: Sequential analysis exhibited a non-significant and inconclusive evidence on fat grafting for pain control in PMPS if this synthesis included the newest RCT. Although the pooled result with unmet expectation of z-score in sequential analysis, it might not fall in futility. If the newest RCT was removed from the synthesis, sequential analysis showed significant but inconclusive evidence on fat grafting for pain control in PMPS. CONCLUSION: There is no conclusive evidence to support or refuse the use of fat grafting in postmastectomy pain control. This topic is worthy of further studies in investigating the effects of fat grafting on pain control amongst patients with PMPS.
