RESUMO
OBJECTIVE: To assess the quality of harms reporting in systematic reviews (SRs) regarding minimally invasive hysterectomies (MIHs). DATA SOURCES: We performed a cross-sectional analysis on SRs addressing MIHs to assess completeness of harms reporting. Hysterectomies are common gynecologic procedures and are associated with complications. Such adverse events can directly affect physician decision making and patient outcomes. Thus, it is important that SRs equally weigh the harms and benefits surrounding MIHs. METHODS OF STUDY SELECTION: On May 15, 2022, we searched MEDLINE (PubMed and Ovid), Embase, Epistemonikos, and the Cochrane Database of Systematic Reviews for SRs with or without a meta-analysis on MIH for any indication. Eligible studies underwent full-text screening, data extraction, harms reporting assessment, and A Measurement Tool to Assess Systematic Reviews-2 quality assessment in a masked, duplicate fashion. The corrected covered area was calculated to indicate any overlap between SR dyads. TABULATION, INTEGRATION, AND RESULTS: A total of 52 SRs met the inclusion criteria for data extraction. We found that >44 of included SRs (of 52; 84.6%) reported >50% of the harms items. Completeness of harms reporting was significantly associated with harms specification as a primary outcome (p <.05). The corrected covered area was 0.60%. CONCLUSION: The harms reporting was more complete than hypothesized, but still had deficiencies throughout, such as inconsistent use of severity scales to classify harms. Even though MIH harms reporting in sample SRs was more complete than other fields of medicine, it was still suboptimal overall and requires refinement.

OBJECTIVES: To evaluate the completeness of harms reporting in systematic reviews (SRs) pertaining to functional endoscopic sinus surgery (FESS). METHODS: Using a cross-sectional study design, we performed a comprehensive search using MEDLINE (PubMed and Ovid), EMBASE, Epistemonikos, and the Cochrane Database of Systematic Reviews databases for SRs regarding FESS on May 15th, 2022. Returns were screened and data were extracted in a masked, duplicate manner. Following established methodology, we extracted general study characteristics, harms items, and overall methodological quality for each SR in our sample. Corrected covered area (CCA) was calculated for SR dyads. For data analysis, using Stata 16.1 we performed a bivariate analysis between variables. RESULTS: Fifty-five SR's were included in our sample after excluding 375 studies that did not meet our inclusion criteria. Of the included SRs, 19 (19/55, 34.5%) did not report harms and 39 (39/55, 70.9%) reported half of the harms items or fewer. Our study found that 23 (23/55, 41.8%) of SRs demonstrated a method of harms data collection, 26 (26/55, 47.3%) of SRs had patients available for harms analysis in their results, and 25 (25/55, 45.5%) of SRs had a balanced discussion of harms and benefits of FESS. Fifty-two SRs were appraised as "critically low" quality using AMSTAR-2. A significant association was found between completeness of harms reporting (Mahady) and whether harms were listed as a primary outcome. No other associations were statistically significant. Two SR dyads had CCAs between 20% and 50% overlap and were compared for unique and shared harms. CONCLUSIONS: Our study demonstrates gaps in harms reporting regarding FESS in SRs. We recommend future studies implement guidelines such as the STROCCS guidelines or the harms extension of the PRISMA guidelines to improve harms reporting. Accurate harms reporting may advance patient safety and promote a more objective risk-benefit analysis for physicians and patients.

BACKGROUND: Owing to the frequent perioperative use of ketorolac tromethamine and its ability to minimise postoperative opioid requirements, it is important to continually reassess harms associated with its use. Our primary objective was to investigate the extent of harms reporting in systematic reviews (SRs) on ketorolac for perioperative pain. METHODS: In May 2022, we conducted a search of major databases, MEDLINE (PubMed and Ovid), Embase, Epistemonikos, and the Cochrane Database of Systematic Reviews to identify eligible SRs on ketorolac for perioperative pain. Screening and data extraction were performed in masked, duplicate fashion. A MeaSurement Tool to Assess systematic Reviews-2 (AMSTAR-2) was used to appraise the methodological quality of included SRs. Corrected covered area (CCA) was calculated to determine overlap of primary studies between SR dyads. RESULTS: A total of 28 SRs evaluating 630 primary studies met the inclusion criteria. Seven SRs (7/28, 25%) reported no harms and 17 SRs (17/28, 60.7%) reported ≤50% of harms items. A significant association was found between completeness of harms reporting and whether harms were specified as a primary outcome (P<0.001). No other associations were statistically significant. Regarding methodological quality, 22 SRs were appraised as 'critically low' (22/28, 78.6%), 5 as 'low' (5/28, 17.9%), and 1 as 'high' (1/28, 3.6%). One SR dyad had a CCA >50% but neither reported harms. CONCLUSIONS: The extent of harms reporting in systematic reviews was inadequate. Given the importance that systematic reviews have on guiding perioperative decision-making, it is essential to improve the completeness of harms reporting.

Esophageal motility disorders (EMD) can have significant effects on quality of life. Patient-reported outcomes (PROs) provide valuable insight into the patient's perspective on their treatment and are becoming increasingly used in randomized controlled trials (RCTs). Thus, our investigation aims to evaluate the completeness of reporting of PROs in RCTs pertaining to EMDs. We searched MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for published RCTs focused on EMDs. Included RCTs were published between 2006 and 2020, reported a primary outcome related to an EMDs, and listed at least one PRO measure as a primary or secondary outcome. Investigators screened and extracted data in a masked, duplicate fashion. Data extraction was carried out using both the CONSORT-PRO adaptation and Cochrane Collaboration Risk of Bias 2.0 tool. We assessed overall mean percent completion of the CONSORT-PRO adaptation and a bivariate regression analysis was used to assess relationships between trial characteristics and completeness of reporting. The overall mean percent completion of the CONSORT-PRO checklist adaptation was 43.86% (SD = 17.03). RCTs with a primary PRO had a mean completeness of 47.73% (SD = 17.32) and RCTs with a secondary PRO was 35.36% (SD = 13.52). RCTs with a conflict of interest statement were 18.15% (SE = 6.5) more complete (t = 2.79, P = .009) than trials lacking a statement. No additional significant associations between trial characteristics and completeness of reporting were found. PRO reporting completeness in RCTs focused on EMDs was inadequate. We urge EMD researchers to prioritize complete PRO reporting to foster patient-centered research for future RCTs on EMDs.

Sickle cell disease significantly impacts one's quality of life (QOL); thus, randomized controlled trials (RCTs) have integrated patient-reported outcomes (PROs) to assess patients' health from their perspective. We aim to evaluate the completeness of reporting of PROs included in sickle cell disease RCTs. We searched MEDLINE, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) for published sickle cell disease RCTs with at least one PRO measure from 2006 to 2021. In a masked, duplicate fashion, two investigators evaluated RCTs using the Consolidated Standards of Reporting in Trials (CONSORT)-PRO adaptation and Cochrane Collaboration Risk of Bias (RoB) 2.0 tool. The primary objective was mean percent completeness of the CONSORT-PRO adaptation. Additional relationships between trial characteristics and completeness of reporting were evaluated. Mean completeness of reporting of RCTs was 41.49% (SD = 20.90). Randomized controlled trials with primary outcomes were more complete (57.50%, SD = 8.33) than RCTs with secondary PROs (33.48%, SD = 20.91). We did not find a significant difference in completion between trials with primary PROs and secondary PROs (t1 = 2.07; p = 0.06). Our secondary objectives included factors that may be associated with completeness of PRO reporting. Of the 12 included studies, five were considered to be overall 'high' RoB (41.67%). In each of the five domains, the majority of studies received 'low' RoB evaluations. Incomplete PRO reporting was common within sickle cell RCTs. Therefore, we recommend future RCTs including PROs should take measures to increase completeness of reporting.

BACKGROUND AND OBJECTIVE: The expanding use of botulinum toxin (BoNT) in medical practice demonstrates the need to highlight whether there is adequate information regarding its safety profile. The aim of our study was to identify completeness of harms reporting for BoNT treatment within systematic reviews (SRs), assess quality of SRs using the AMSTAR-2 tool, and determine the degree of overlap among primary studies within each SR. METHODS: On May 31, 2022, we searched Embase, Epistemonikos, MEDLINE, and the Cochrane Database of Systematic Reviews for SRs on BoNT therapy. Screening and data extraction were performed in a masked, duplicate fashion. AMSTAR-2 was used to evaluate the methodological quality of included SRs. Corrected covered area (CCA) was calculated for SR dyads. RESULTS: Of the 90 included SRs, we found that 70 completed less than 50% of harms items. The most reported items were BoNT as a favorable intervention (73/90, 81.1%) and harms as a primary outcome (72/90, 80.0%). The least reported items were grades and severity scales used to classify harms (8/90, 8.9%) and number of treatment discontinuations in each arm (10/90, 11.1%). Eighty-three SRs were rated "critically low" (83/90, 92.2%), while 5 SRs were rated "high" (5/90, 5.6%) via AMSTAR-2 tool. Significant associations were found between completion of harms reporting and: (1) a "critically low" appraisal on AMSTAR-2 tool (p = 0.0060) and (2) whether harms was reported as a primary outcome (p = 0.0001). The total CCA overlap was determined to be 0.8%. CONCLUSION: Our results demonstrate that harms are underreported within BoNT SRs. Because healthcare professionals often refer to SRs to guide clinical decision making, it is important to continue to explore shortcomings among BoNT literature in future studies.

Background Context: Laminectomy is a common vertebral decompression procedure that has multiple potential adverse events which are not always reported in SRs. Purpose: To evaluate the completeness of harms reporting in systematic reviews (SRs) on laminectomy. Study Design: Cross-sectional analysis. Methods: Eligible studies were SRs that evaluated laminectomy for any indication. MEDLINE (PubMed and Ovid), Embase, Epistemonikos, and the Cochrane Database of Systematic Reviews were searched in May 2022 to locate studies for inclusion. Screening and data extraction on harms reporting and study characteristics were performed in duplicate. AMSTAR-2 was used to evaluate the methodological quality of included SRs. Corrected covered area (CCA) was calculated for SR pairs. Results: We included 26 SRs comprising 426 primary studies. Most SRs studied laminectomy for spinal stenosis, declared harms as a secondary outcome, and lacked or did not mention funding. Two SRs completely omitted harms, 9 had between 0% and 50.0% completion of harms items, and 15 had more than 50.1% completion. AMSTAR-2 graded 25 SRs (25/26, 96.2%) as 'critically low' and 1 SR (1/26, 3.8%) as 'low'. We found a statistically significant association between completeness of harms reporting and outcome specification. No other associations were statistically significant. Three SR pairs had CCAs >50% and were compared for unique and shared harms. Conclusions: The completeness of harms reporting in SRs was inadequate. Because SRs often serve as tools for constructing clinical practice guidelines and clinical decision making, improvements must be made to enhance and refine harms reporting.
RESUMO
BACKGROUND: Patient-reported outcomes (PROs) are increasingly used in randomized controlled trials (RCTs) to foster patient-centered healthcare. The aim of this investigation was to assess the completeness of reporting of PROs in RCTs pertaining to cystic fibrosis (CF). METHODS: We searched MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for RCTs concerning CF that included PROs as a primary or secondary outcome. The RCTs were assessed by 2 independent investigators using an adaptation of the Consolidated Standards of Reporting Trials for Patient-Reported Outcomes (CONSORT-PRO) and the Cochrane Risk of Bias (RoB) 2.0 assessment. We calculated the mean completion percentage of adherence to the CONSORT-PRO adaptation and used bivariate regression models to evaluate for associations with particular trial characteristics. RESULTS: Our systematic search returned 2302 potential studies. Fifty-nine eligible RCTs were included after full-text screening. The RCT mean completeness of reporting was 38.38% (SD = 12.74). We found the following associations between trial characteristics and completeness of PRO reporting: (1) significantly higher reporting completeness for RCTs published in journals requiring adherence to the CONSORT guideline (p-value = 0.049), (2) improved reporting completeness in studies with 'some concerns' of RoB versus 'high' RoB (p-value = 0.042), and (3) significantly better reporting completeness when the PRO is the primary outcome of a RCT (p-value = 0.006). CONCLUSION: Inadequate PRO reporting exists within RCTs focused on CF. Given that CF has substantial effects on quality of life, PROs are imperative to understand patients' experiences. We believe greater adherence to CONSORT-PRO will promote the standardization of PRO reporting and will facilitate comprehension of PROs by stakeholders, patients, and clinicians.

BACKGROUND AND OBJECTIVES: To identify the similarities and differences in data-sharing policies for clinical trial data that are endorsed by biomedical journals, funding agencies, and other professional organizations. Additionally, to determine the beliefs, and opinions regarding data-sharing policies for clinical trials discussed in articles published in biomedical journals. METHODS: Two searches were conducted, a bibliographic search for published articles that present beliefs, opinions, similarities, and differences regarding policies governing the sharing of clinical trial data. The second search analyzed the gray literature (non-peer-reviewed publications) to identify important data-sharing policies in selected biomedical journals, foundations, funding agencies, and other professional organizations. RESULTS: A total of 471 articles were included after database search and screening, with 45 from the bibliographic search and 426 from the gray literature search. A total of 424 data-sharing policies were included. Fourteen of the 45 published articles from the bibliographic search (31.1%) discussed only advantages specific to data-sharing policies, 27 (27/45; 60%) discussed both advantages and disadvantages, and 4 (4/45; 8.9%) discussed only disadvantages specific. A total of 216 journals (of 270; 80%) specified a data-sharing policy provided by the journal itself. One hundred industry data-sharing policies were included, and 32 (32%) referenced a data-sharing policy on their website. One hundred and thirty-six (42%) organizations (of 327) specified a data-sharing policy. CONCLUSION: We found many similarities listed as advantages to data-sharing and fewer disadvantages were discussed within the literature. Additionally, we found a wide variety of commonalities and differences-such as the lack of standardization between policies, and inadequately addressed details regarding the accessibility of research data-that exist in data-sharing policies endorsed by biomedical journals, funding agencies, and other professional organizations. Our study may not include information on all data sharing policies and our data is limited to the entities' descriptions of each policy.

Patient-reported outcomes (PROs) in randomized controlled trials pertaining to inflammatory bowel disease are important in identifying patients' perspective of treatment. Incompletely reported PROs within trials could misrepresent information for clinicians and may contribute to treatment which lacks accommodation of patient input. Our study evaluates completeness of reporting of PROs and risk of bias (RoB) to identify how well trialists are adhering to known resources for trials. We used MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify eligible trials from 2006 to 2020 with at least 1 PRO measure related to inflammatory bowel disease. The trials were screened in duplicate using Rayyan. We then compared trial completion of reporting to the Consolidated Standards of Reporting Trials (CONSORT)-PRO adaptation, and assessed RoB using the Cochrane Collaboration RoB 2.0 tool. To measure trial and reporting characteristics, we performed bivariate regression analyses. Among a sample of 29 trials, the mean completion percentage for CONSORT-PRO was 46.77%. We found PROs as a secondary outcome had significantly lower CONSORT-PRO reporting (p<0.05). In addition, per cent completeness of reporting was significantly higher with both a 'therapy' intervention, and trials published following the development of CONSORT-PRO (p<0.05). Incomplete PRO reporting is common in trials focused on inflammatory bowel disease. This suboptimal reporting indicates the need for adherence to reporting guidelines. Trialists should use the CONSORT-PRO checklist, as endorsed by Patient-Reported Outcomes Tools: Engaging Users and Stakeholders, to assess their studies in order to enhance reporting adherence.

Purpose: To evaluate the completeness of patient-reported outcomes (PROs) reporting using Consolidated Standards of Reporting Trials Patient-Reported Outcome (CONSORT-PRO) in randomized controlled trials (RCTs) involving rotator cuff injuries. Methods: We performed a comprehensive search of MEDLINE, Embase, and Cochrane Central Register of Controlled Trials for published RCTs focused on rotator cuff injuries that included at least one PRO measure. We included RCTs published from 2006 to 2020. Investigators extracted data from RCTs using the CONSORT-PRO and evaluated each RCT using the Cochrane Risk of Bias 2.0 tool. Our primary objective was to evaluate the mean completion percentage of CONSORT-PRO. Our secondary objective used bivariate regression analyses to explore the relationship between trial characteristics and completeness of reporting. Results: The initial search returned 467 results, with 33 published RCTs meeting the prespecified inclusion criteria. The mean CONSORT-PRO completeness across all included RCTs was 49.7% (standard deviation 15.43). An increase in sample size was associated with an increase in mean completeness of reporting (t = 2.31; P = .028). The Risk of Bias assessment found 29 (of 33, 87.88%) RCTs had "some concerns" for bias. We did not find any additional significant associations between completeness of reporting and trial characteristics. Conclusions: Randomized controlled trials involving rotator cuff injuries frequently use PRO measures as primary outcomes. Reporting of these PRO measures is suboptimal and may benefit from rigorous standardization. Clinical Relevance: PRO measures are increasingly incorporated as primary or secondary outcomes of RCTs. Appropriate reporting and use of state-of-the-art PRO measures may improve the dissemination of clinical knowledge from RCTs to guide treatment and determine intervention effectiveness. With increased adoption of Patient-Reported Outcome Measure Information System and adherence to CONSORT-PRO, orthopaedic literature may improve PRO reporting to optimize the interpretability of PROs and facilitate patient-centered care.
RESUMO
OBJECTIVES: Peptic ulcer disease (PUD) can significantly affect quality of life (QoL). These QoL outcomes are often patient-reported, and their inclusion in clinical trials supplements efficacy outcomes to provide the patients' perspective. This assese existing literature for completeness of PRO reporting across randomized controlled trials (RCTs) evaluating PUD. METHODS: This meta-epidemiological, cross-sectional study that assessed completeness of reporting among RCTs addressing management of PUD. We conducted a comprehensive literature search] to identify RCTs with a PRO as a primary or secondary outcome. These RCTs were assessed for completion of reporting according to the PRO adaptation of CONSORT checklist. RCTs were also assessed for Risk of Bias (RoB) using the Cochrane RoB 2.0 tool. RESULTS: Masked, duplicate screening of 829 results = yielded a final sample of 35 RCTs. The average completeness of reporting was 32.9% according to the CONSORT-PRO adaptation. Twenty-one (of 35; 60%) of the RCTs were assessed as having 'high' risk of bias and nine (of 35; 25.71%) were assessed as having 'some concerns' for risk of bias. Bivariate regression found completeness of reporting to be positively associated with increased PRO follow-up duration, sample size, and studies with conflicts of interest. CONCLUSION: RCTs examining the treatment and prevention of PUD with PROs as an outcome measure have deficient reporting and 'high' risk of bias according to the CONSORT-PRO and Cochrane RoB guidelines.

Major depressive disorder (MDD) is a multifaceted disease that profoundly affects quality of life. Patient reported outcomes (PROs) are used in randomized controlled trials (RCTs) to better understand patient perspectives on interventions. Therefore, we sought to assess the completeness of reporting PROs in RCTs addressing MDD. We identified RCTs evaluating MDD containing a PRO measure published between 2016 and 2020 from MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials. Inclusion of studies was performed in duplicate. The completion of reporting of RCTs was assessed using the Consolidated Standards of Reporting Trials (CONSORT-PRO) adaptation. Bivariate regression analyses were used to evaluate reporting completeness and trial characteristics. A total of 49 RCTs were included in our analysis, with a mean CONSORT-PRO completion score of 56.7% (SD = 17.3).Our findings show a significant association with completeness of reporting and the following: secondary PRO trials were less completely reported as compared to primary PRO trials (t = -3.19, p = .003); studies with a follow-up period between six months and year were more completely reported as compared to three months or less (6 months to a year, t = 2.34, p = .024); and increased trial sample size was associated with more completeness of reporting (t = 3.17, p = .003). As compared to brain stimulation, the intervention types classified as combination, other, and psychotherapy had greater completeness of reporting (combination, t = 2.35, p = .024; other, t = 3.13, p = .003; psychotherapy, t = 3.41, p = .001). There were no other significant findings. Our study found the completeness of PRO reporting to be inconsistent in RCTs regarding MDD. Moreover, we advocate for the need to establish a core outcome set relevant to the management of adults diagnosed with MDD and facilitate training on the application of PRO data.

BACKGROUND: Multiple Sclerosis significantly affects quality of life, which is often measured by patient-reported outcomes. The incorporation of patient-reported outcomes within clinical trials supplements the efficacy of outcomes in order to provide a patient's perspective for clinicians. Our objective was to evaluate current literature for completeness of reporting of PROs in randomized controlled trials (RCTs) for the management of MS. METHODS: We used MEDLINE, Embase, and Cochrane Central Register of Controlled Trials to search for RCT publications investigating the management of MS. After duplicate screening via Rayyan, RCTs fitting our inclusion criteria were abstracted employing the Consolidated Standards of Reporting Trials - Patient-Reported Outcome (CONSORT-PRO) adaptation and the Cochrane Collaboration Risk of Bias (RoB) 2.0 tool. Mean percent completion of an adaptation of CONSORT-PRO was calculated to address completeness of reporting. In addition, bivariate regression models were used to evaluate relationships between trial characteristics and completeness of reporting. RESULTS: Our search returned 3,966 results and 92 RCTs were included for data abstraction and analysis. We found an overall completion of 48.68% (SD=19.03). Sixty-five (of 92; 70.65%) of the RCTs were evaluated as having 'high' RoB. There were significant associations between completeness of reporting and the following: mention of CONSORT within published RCTs (t=2.55, p=.013), length of PRO follow-up (t=2.9, p=.005; t=2.14, p=.035), and sample size (t=3.12, p=.002). No other significant associations were found. CONCLUSION: Our study found incomplete adherence to the CONSORT-PRO adaptation among RCTs pertaining to MS. Of the most underreported items, the failure to report a hypothesis and define an approach to missing data threaten the validity of the evidence acquired from RCTs. Furthermore, PROs provide an opportunity to supplement trial outcomes with the patient's perspective. Thus, trialists of future RCTs may improve PRO reporting with increased adherence to the CONSORT-PRO adaptation.

OBJECTIVES: Randomized controlled trial (RCT) discontinuation and nonpublication are potential mechanisms of waste in resources and lead to decreased advancement of medical science and compromised ethical issues in all specialties. However, the prevalence of discontinued or unpublished RCTs regarding common pediatric otolaryngology disorders and interventions remains unclear. STUDY DESIGN: Cross-sectional analysis. METHODS: Retrospective analysis of common pediatric otolaryngology RCTs registered in ClinicalTrials.gov up until November 2, 2018. Data were collected from the registry, and publication status was identified. If a reason for trial discontinuation or nonpublication was not identified through a systematic search, corresponding trialists were contacted through email. RESULTS: After exclusion, 260 RCTs were included for analysis. Analysis found 198 (76%) RCTs were completed, and 62 (24%) trials were discontinued. The most commonly reported reasons for RCT discontinuation were program termination by sponsor or management (7/24; 29.2%), lack of participant enrollment, difficulty recruiting, or slow accrual (7/24; 29.2%). A total of 192 (192/260; 73.8%) published RCTs and 68 (68/260; 26.2%) unpublished RCTs were identified. Twenty-six (26/62; 42%) of the discontinued RCTs reached publication, while 36 (58%) remained unpublished. Regarding the completed RCTs, 166 of 198 (83.8%) completed trials reached publication, while 32 (32/198; 16.2%) remained unpublished after trial completion. CONCLUSIONS: Approximately 1 in 4 of included RCTs were discontinued or did not reach publication. Findings suggest further guidance is needed for RCTs regarding common pediatric otolaryngology disorders and interventions. LEVEL OF EVIDENCE: NA.

OBJECTIVES: To identify, quantify, and characterize the presence of spin-specific strategies leading to misrepresentation of study results-in the abstracts of systematic reviews and meta-analyses of Ménière's disease treatment. METHODS: Using a cross-sectional design, we searched MEDLINE and Embase on May 28, 2020, for systematic reviews and meta-analyses focused on Ménière's disease treatment. Returned searches were screened, and data were extracted in a masked, duplicate fashion. RESULTS: Our sample included 36 systematic reviews and meta-analyses. Of the 36 included studies, 22 (61.1%) abstracts contained spin while 14 (38.9%) did not. The most common spin types were selective reporting of benefit (10/36, 27.8%) or harm (8/36, 22.2%). Other types of spin occurred when findings were extrapolated to the global improvement of the disease (5/36, 13.9%), beneficial effects were reported with high risk of bias in primary studies (3/36, 8.3%), and when beneficial effects were extrapolated to an entire class of interventions (1/36, 2.8%). No instances of other spin types occurred. Abstracts containing spin were substantively associated with studies of critically low methodological quality compared with studies with low and moderate quality. No studies had a methodological rating of high quality. No associations were observed between spin and intervention types, journal recommendation of adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses, or funding. We found a negative correlation (r = -.31) between abstract word limit and presence of spin. CONCLUSIONS: Our study highlights that spin in the abstracts of systematic reviews of Ménière's disease is common, and it further enhances the discussion surrounding spin in abstracts of scientific research. Spin in an abstract does not discredit a study's findings; however, its occurrence should be eliminated.
