Sars-CoV2 vaccine hesitancy in Italy: A survey on subjects with diabetes.

BACKGROUND AND AIMS: Vaccine Hesitancy (VH) is a relevant obstacle for the COVID-19 vaccination campaign. The aim of this study is to assess the proportion of subjects unwilling to vaccinate among patients with type 1 (T1DM) and 2 (T2DM) diabetes, exploring factors associated with VH. METHODS AND RESULTS: A purposely created interview was delivered from physicians to a consecutive series of adult (>18 years) subjects with diabetes referring to the Diabetes Outpatient Clinic of Careggi Hospital, Florence, from January 1st to April 30th 2021. Out of 502 subjects enrolled, 92 were vaccine hesitant respondents (18.3%); the corresponding figure for T1DM and T2DM was 13.0% (N = 14), and 19.9% (N = 78), respectively. After adjusting for age, higher HbA1c (1.07 [1.02-1.13], p = 0.008) and triglycerides levels (1.03 [1.01-1.06], p = 0.011) were positively associated with VH, among patients with T1DM. At multivariate analysis, after adjusting for age, creatinine, and statin use, patients with T2DM affected by obesity (9.98 [4.89-9.59], p < 0.01) and with lower levels of creatinine (0.36 [0.21-0.54], p = 0.029) were more likely to refuse COVID vaccination. CONCLUSIONS: Hesitancy toward COVID-19 vaccination among subjects with diabetes is not negligible and seems to be more prevalent in individuals with lower adherence to medical prescriptions and/or reduced concerns over their health. This suggests the need for specific interventions to increase awareness and counter prejudices on vaccines.

Efficacy and safety of glucose-lowering agents in patients with type 2 diabetes: A network meta-analysis of randomized, active comparator-controlled trials.

AIM: Aim of the present network meta-analysis (NMA) is the comparison across glucose-lowering drugs (GLA) concerning their effects on glucose control, body weight, hypoglycemia, gastrointestinal adverse events, and quality of life. DATA SYNTHESIS: This NMA includes randomized clinical trials comparing different head-to-head comparison trials with EMA-approved GLA in type 2 diabetes, with a duration of ≥52 weeks. All drugs have to be administered at the maximal approved dose. Primary endpoints were HbA1c at 12, 52, and 104+ weeks. Secondary endpoints were body weight, quality of life, hypoglycemia, and gastrointestinal disorders. Indirect comparisons of different GLA were performed by NMA choosing metformin as reference. The standardized difference in means (SDM) and Mantel-Haenzel Odds Ratio [MH-OR] (using random-effect models) with 95% Confidence Intervals were calculated for categorical and continuous variables, respectively. We included 68 trials fulfilling all inclusion criteria. At 12 weeks, when considering indirect comparisons, insulin secretagogues (IS) were associated with a significantly greater reduction in comparison with metformin (SDM, -0.3 [-0.4;-0.2]%); a significantly lower efficacy was observed for pioglitazone. At 52 weeks, IS were no longer associated with a greater reduction of HbA1c; whereas a significant decrease in HbA1c was observed for GLP-1 RA (SDM, -0.2 [-0.1;-0.3]%). At 104+ weeks, only SGLT-2 inhibitors showed a significantly greater HbA1c reduction (SDM, -0.2 [-0.1;-0.3]%), whereas sulfonylureas and insulin showed a significantly lower efficacy (SDM, 0.1 [0.0; 0.2]%), and 0.4 [0.3; 0.5]%, respectively). CONCLUSIONS: The results of this meta-analysis should be considered together with evidence on long-term outcomes for selecting the most appropriate drugs for individual patients.

Association between different screening strategies for SARS-CoV-2 and deaths and severe disease in Italy.

BACKGROUND: The WHO recommends testing any suspected person with Severe Acute Respiratory Syndrome CoronaVirus-2 (SARS-CoV-2), in order to limit the spread of the epidemic. In Italy, some Regions opted for extensive testing, whereas others limited tests to selected subjects. To assess the influence of different strategies, we examined the incidence of death and severe cases in Italy. METHODS: Data on new cases of SARS-CoV-2, number of tests, deaths and admissions to Intensive Care Units (ICU) were retrieved in each Italian Region, from 24 February to 18 March 2020. As an index of different screening strategies, the number of tests/positive test results (P/T) ratio as of 7 March 2020, was considered. The cumulative number of deaths and of new severe cases, between March 23 and 25 was recorded. The association of those two outcomes with the number of P/T ratio was assessed using linear regression models. RESULTS: In the interval between March 23 and 25, recorded deaths (*million inhabitants) were 14 (3-54), whereas severe cases were 31 (10-112). Both the number of deaths and that of severe cases showed a significant correlation (R2 .57 and .41, with P < .01) with the P/T ratio. Deaths and severe cases were associated with higher mean personal income and lower density of General Practioners (GPs). The association of P/T with severe cases and deaths retained statistical significance after adjusting for mean personal income (R2 .30 and .41, respectively; both P = .04) and GPs density (R2 .21 and .19, respectively; both P = .03). CONCLUSIONS: A more aggressive screening strategy for SARS-Cov-2, was associated with lower rates of death and severe disease in Regions of Italy.

Effectiveness of different advanced wound dressings versus standard of care for the management of diabetic foot ulcers: a meta-analysis of randomized controlled trials for the development of the Italian guidelines for the treatment of diabetic foot syndrome.

AIM: to assess the effects of advanced wound dressings (AWD) commonly used in the treatment of predominantly neuropathic diabetic foot ulcers (DFU) The present meta-analysis was designed to support the development of the Italian Guidelines for the Treatment of Diabetic Foot Syndrome (DFS). METHODS: A Medline and Embase search were performed up to April 1st, 2024 collecting all RCTs including diabetic patients or reporting subgroup analyses on diabetic patients with DFU comparing AWD with placebo/standard of care (SoC), with a duration of at least 12 weeks. Prespecified endpoints were: ulcer healing (principal), time-to-healing, frequency of dressings change, major and minor amputation, pain, and all-cause mortality. AWD assessed were: alginates; foam, hydrocolloids, hydrogels, hyaluronic acid, hemoglobin spray, silver-impregnated, sucrose octasulfate-impregnated, honey-impregnated, micro-organism-binding, and protease-modulating matrix dressings. Mantel-Haenzel Odds ratios and 95% confidence intervals (MH-OR, 95% CIs) were either calculated or extracted directly from the publications. Weighted mean differences (WMD) and 95% CIs were calculated for continuous variables. RESULTS: Fifteen studies fulfilled all inclusion criteria. Participants treated with AWD had a significantly higher ulcer healing rate and shorter time-to-healing in comparison with SoC/placebo (MH-OR 1.50 [0.80, 2.79], p = 0.20 and WMD:: - 24.38 [- 42.90, - 5.86] days, p = 0.010). No other significant effect on the above reported prespecified endpoints were observed. For the primary endpoint, the quality of evidence was rated as "moderate". CONCLUSIONS: In conclusion, AWD, particularly sucrose-octasulfate, hydrogels, hyaluronic acid, and honey dressings, can actively promote wound healing and shortening time-to-healing in patients with DFU.

Bypass surgery versus endovascular revascularization for occlusive infrainguinal peripheral artery disease: a meta-analysis of randomized controlled trials for the development of the Italian Guidelines for the treatment of diabetic foot syndrome.

To report a review and meta-analysis of all randomized controlled trials (RCTs) comparing bypass surgery (BS) and endovascular treatment (ET) in infrainguinal peripheral arterial disease (PAD) for several endpoints, such as major and minor amputation, major adverse limb events (MALEs), ulcer healing, time to healing, and all-cause mortality to support the development of the Italian Guidelines for the Treatment of Diabetic Foot Syndrome (DFS). A MEDLINE and EMBASE search was performed to identify RCTs, published since 1991 up to June 21, 2023, enrolling patients with lower limb ischemia due to atherosclerotic disease (Rutherford I-VI). Any surgical BS or ET was allowed, irrespective of the approach, route, or graft employed, from iliac to below-the-knee district. Primary endpoint was major amputation rate. Secondary endpoints were amputation-free survival major adverse limb events (MALEs), minor amputation rate, all-cause mortality, ulcer healing rate, time to healing, pain, transcutaneous oxygen pressure (TcPO2) or ankle-brachial index (ABI), quality of life, need for a new procedure, periprocedural serious adverse events (SAE; within 30 days from the procedure), hospital lenght of stay, and operative time. Twelve RCTs were included, one enrolled two separate cohorts of patients, and therefore, the studies included in the analyses were 13. Participants treated with ET had a similar rate of major amputations to participants treated with BS (MH-OR 0.85 [0.60, 1.20], p = 0.36); only one trial reported separately data on patients with diabetes (N = 1), showing no significant difference between ET and BS (MH-OR: 0.67 [0.09, 5.13], p = 0.70). For minor amputation, no between-group significant differences were reported: MH-OR for ET vs BS: 0.83 [0.21, 3.30], p = 0.80). No significant difference in amputation-free survival between the two treatment modalities was identified (MH-OR 0.94 [0.59, 1.49], p = 0.80); only one study reported subgroup analyses on diabetes, with a non-statistical trend toward reduction in favor of ET (MH-OR 0.62 [0.37, 1.04], p = 0.07). No significant difference between treatments was found for all-cause mortality (MH-OR for ET vs BS: 0.98 [0.80, 1.21], p = 0.88). A significantly higher rate of MALE was reported in participants treated with ET (MH-OR: 1.44 [1.05, 1.98], p = 0.03); in diabetes subgroup analysis showed no differences between-group for this outcome (MH-OR: 1.34 [0.76, 2.37], p = 0.30). Operative duration and length of hospital stay were significantly shorter for ET (WMD: - 101.53 [- 127.71, - 75.35] min, p < 0.001, and, - 4.15 [- 5.73, - 2.57] days, p < 0.001 =, respectively). ET was associated with a significantly lower risk of any SAE within 30 days in comparison with BS (MH-OR: 0.60 [0.42, 0.86], p = 0.006). ET was associated with a significantly higher risk of reintervention (MH-OR: 1.57 [1.10, 2.24], p = 0.01). No significant between-group differences were reported for ulcer healing (MH-OR: 1.19 [0.53, 2.69], p = 0.67), although time to healing was shorter (- 1.00 [0.18, 1.82] months, p = 0.02) with BS. No differences were found in terms of quality of life and pain. ABI at the end of the study was reported by 7 studies showing a significant superiority of BS in comparison with ET (WMD: 0.09[0.02; 0.15] points, p = 0.01). The results of this meta-analysis showed no clear superiority of either ET or BS for the treatment of infrainguinal PAD also in diabetic patients. Further high-quality studies are needed, focusing on clinical outcomes, including pre-planned subgroup analyses on specific categories of patients, such as those with diabetes and detailing multidisciplinary team approach and structured follow-up.

Prevention of foot ulcers recurrence in patients with diabetes: a systematic review and meta-analysis of randomized controlled trials for the development of the italian guidelines for the treatment of diabetic foot syndrome.

AIM: To compare the effectiveness of preventive interventions in reducing reccurrent diabetic foot ulcers. Meta-analysis (MA) was conducted to address clinical questions on this topic of the Italian guidelines on diabetic foot. METHODS: This MA includes randomized controlled trials evaluating the effectiveness of various preventive interventions, namely: treatment of pre-ulcerative foot lesions, structured educational programs, psychological interventions and the use of therapeutic footwear to relieve plantar pressure in people with diabetes mellitus and a history of previous ulcers. RESULTS: A total of 731 studies were identified and 14 were considered eligible for the analysis. We found that treatments of pre-ulcerative foot lesions did not provide any statistically significant effects (MH-OR: 0.84 [0.31, 2.33], p = 0.74, I2 = 38%). Conversely, structured educational programs were associated with a trend toward reduction of ulcer recurrence risk (MH-OR: 0.13 [0.01, 1.64], p = 0.10, I2 = 88%). No randomized controlled studies assessing the efficacy of psychological interventions have been retrieved. The use of therapeutic footwears can effectively reduce the risk of reulceration in diabetic patients with an history of previous DFU, in particular prefabricated rigid-soled therapeutic footwears showed a significant reduction of the risk of ulcer recurrence in comparison with semirigid soles (MH-OR: 0.17 [0.05, 0.57], p = 0.004). CONCLUSIONS: The study provides low-certainty evidence that, among preventive strategies in patients with previous DFU, rigid-sole therapeutic footwear and structured education programs are capable of reducing the risk of foot re-ulceration.

Upcoming Italian clinical practice guidelines on endoscopic bariatric treatment of overweight and obesity: design and methodological aspects.

Obesity/overweight and its complications are a growing problem in many countries. Italian Society of Bariatric and Metabolic Surgery for Obesity (Società Italiana di Chirurgia dell'Obesità e delle Malattie Metaboliche-SICOB) decided to develop the first Italian guidelines for the endoscopic bariatric treatment of obesity. The creation of SICOB Guidelines is based on an extended work made by a panel of 44 members and a coordinator. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology has been used to decide the aims, reference population, and target health professionals. Clinical questions have been created using the PICO (patient, intervention, comparison, outcome) conceptual framework. We will perform systematic reviews, formal meta-analyses, and network meta-analyses for each PICO and critical outcomes aimed at assessing and rating the efficacy and safety of endoscopic bariatric procedures in comparison with either no interventions, lifestyle interventions, or approved anti-obesity treatments in trials with a follow-up of at least 52 weeks. For PICO on temporary endoscopic bariatric treatments, we will also consider RCT with a minimum duration of 6 months. The panel proposed 8 questions, organized into four domains: A. Indication for endoscopic bariatric surgery; B. Revisional surgery; C. Temporary gastric and duodenal-jejunal procedures; D. Endoscopic diagnosis/treatment of bariatric and metabolic surgery complications. These guidelines will apply to patients aged ≥ 14 years) with body mass index (BMI) ≥ 27 kg/m2 and requiring endoscopic bariatric surgery or endoscopic diagnostic and/or therapeutic procedures. The areas covered by the clinical questions included indications of endoscopic bariatric surgery, types of surgery, revisional surgery, and management of bariatric and metabolic surgery complications.

The identification of prediabetes condition with ARIC algorithm predicts long-term CV events in patients with erectile dysfunction.

INTRODUCTION: The Atherosclerosis Risk in Communities (ARIC) algorithm is one of the most efficient instruments for the prediction of incident type 2 diabetes. Recently, it has been shown to predict another relevant cardiovascular (CV) risk factor, such as chronic kidney disease. AIM: To verify whether, in patients with erectile dysfunction (ED), the use of ARIC diabetes risk score might improve the efficacy in predicting major CV events of other CV risk algorithms specifically developed for the assessment of CV risk. METHODS: A consecutive series of 2,437 men (mean age 52.5 ± 12.9 years) attending our outpatient clinic for sexual dysfunction was retrospectively studied. A subset of this sample (N = 1,687) was enrolled in a longitudinal study (mean follow-up of 4.3 ± 2.6 years). MAIN OUTCOME MEASURES: The assessment of metabolic risk was evaluated with the ARIC algorithm. The assessment of CV risk was evaluated using the Progetto Cuore risk engine. RESULTS: In the cross-sectional study, ARIC score was inversely related with testosterone levels, sexual functioning, and penile blood flow. When longitudinal sample was analyzed, higher baseline ARIC score significantly predicted major adverse cardiovascular event (MACE) even when subjects with diabetes mellitus at baseline were excluded from the analysis (hazard ratio = 1.522 [1.086-2.135]; P = 0.015 for trend). In addition, among subjects classified as "low risk" (CV risk <20% at 10 years corresponding to <9% at 4.3 years) by Progetto Cuore, a receiving operating curve (ROC) analysis for ARIC (vs. MACE) allowed the identification of a threshold of 0.22, which had a positive predictive value for 4.3-year MACE of 9%. Applying the ARIC score (with a threshold of 0.22) to Progetto Cuore "low-risk" subjects, we could classify as "at high risk" 89.8% of subjects with incident MACE vs. 79.6% with Progetto Cuore only. CONCLUSIONS: In patients with ED, identifying prediabetes, even with algorithms, predicts long-term CV events.

Serum PSA as a predictor of testosterone deficiency.

INTRODUCTION: The relationship between serum prostate-specific antigen (PSA) and testosterone (T) levels is still controversial. According to the "saturation hypothesis," a significant relationship is apparent only in the low T range. AIM: To verify whether, in a large sample of male subjects seeking medical care for sexual dysfunction (SD), PSA might represent a reliable marker of T levels. METHODS: A consecutive series of 3,156 patients attending our unit for SD was studied. Among them, only subjects without history of prostate disease and with PSA levels<4 ng/mL (N=2,967) were analyzed. MAIN OUTCOME MEASURES: Several hormonal and biochemical parameters were studied, along with structured interview on erectile dysfunction (SIEDY), ANDROTEST, and PsychoANDROTEST. RESULTS: Receiver operating characteristic curve analysis for predicting severe hypogonadism (T<8 nmol/L) showed an accuracy of PSA=0.612±0.022 (P<0.0001), with the best sensitivity and specificity at PSA<0.65 ng/mL (65.2% and 55.5%, respectively). In the entire cohort, 254 subjects (8.6%) showed T<8 nmol/L and, among them, more than half (N=141, 4.8%) had PSA<0.65 ng/mL. After adjusting for age, low PSA was associated with hypogonadism-related features (i.e., delayed puberty, lower testis volume) and associated conditions, such as metabolic syndrome (hazard ratio [HR]=1.506 [1.241-1.827]; P<0.0001), type 2 diabetes (HR=2.044 [1.675-2.494]; P<0.0001), and cardiovascular diseases (HR=1.275 [1.006-1.617]; P=0.045). Furthermore, low PSA was associated with impaired sex- and sleep-related erections. The association between low PSA and hypogonadal symptoms and signs as well as with metabolic syndrome was retained even after adjusting for T levels. Sensitivity and positive predictive values of low PSA increased, whereas specificity and negative predictive value decreased as a function of age. CONCLUSIONS: PSA is a marker of T concentrations and it may represent a new tool in confirming hypogonadism. The determination of PSA levels might give insights not only on the circulating levels of total T but also on its active fractions.

Two unconventional risk factors for major adverse cardiovascular events in subjects with sexual dysfunction: low education and reported partner's hypoactive sexual desire in comparison with conventional risk factors.

INTRODUCTION: The classification of subjects as low or high cardiovascular (CV) risk is usually performed by risk engines, based upon multivariate prediction algorithms. However, their accuracy in predicting major adverse CV events (MACEs) is lower in high-risk populations as they take into account only conventional risk factors. AIM: To evaluate the accuracy of Progetto Cuore risk engine in predicting MACE in subjects with erectile dysfunction (ED) and to test the role of unconventional CV risk factors, specifically identified for ED. METHODS: A consecutive series of 1,233 men (mean age 53.33 ± 9.08 years) attending our outpatient clinic for sexual dysfunction was longitudinally studied for a mean period of 4.4 ± 2.6 years. MAIN OUTCOME MEASURE: Several clinical, biochemical, and instrumental parameters were evaluated. Subjects were classified as high or low risk, according to previously reported ED-specific risk factors. RESULTS: In the overall population, Progetto Cuore-predicted population survival was not significantly different from the observed one (P = 0.545). Accordingly, receiver operating characteristic (ROC) analysis shows that Progetto Cuore has an accuracy of 0.697 ± 0.037 (P < 0.001) in predicting MACE. Considering subjects at high risk according to ED-specific risk factors, the observed incidence of MACE was significantly higher than the expected for both low educated and patients reporting partner's hypoactive sexual desire (HSD, both <0.05), but not for other described factors. The area under ROC curves of Progetto Cuore for MACE in subjects with low education and reported partner's HSD were 0.659 ± 0.053 (P = 0.008) and 0.550 ± 0.076 (P = 0.570), respectively. CONCLUSION: Overall, Progetto Cuore is a proper instrument for evaluating CV risk in ED subjects. However, in ED, other factors such as low education and partner's HSD concur to risk profile. At variance with low education, Progetto Cuore is not accurate enough to predict MACE in subjects with partner's HSD, suggesting that the latter effect is not mediated by conventional risk factors included in the algorithm.

Major Amputation In Non-Healing Ulcers: Outcomes and Economic Issues. Data from a Cohort of Patients with Diabetic Foot Ulcers.

Background: Foot ulcers have a relevant economic impact on Health Care Systems and the cost-effectivenesseffectiveness of options is not clear. The aim of this study was the assessment of costs for ulcers treatment after 6, 12, and 18 months of follow-up, compared to those for major amputation. Methods: A retrospective study was carried out on 196 types 2 diabetic patients with foot ulcers. The principal endpoints were 1) the proportion of recovered patients among those with ulcers not healed after 6 and 12 months; 2) the assessment of direct costs for treatment of ulcers 6, 12, and 18 months of follow-up, as compared to the cost of major amputation. The economic evaluation was performed considering the perspective of the local health system. Results: Out of 196 patients, 85(46.2%), 131(71.6%), and 140(85.9%) healed within 6, 12, and 18 months, respectively. The average health cost during the 18-month follow-up was 5402€ per patient. We calculated hypothetical costs for three different scenarios, in which patients who did not heal within 6 months underwent a major amputation at 6, 1,2, or 18 months. Costs for the standard of care for all these scenarios (6,094, 7,256, and 7649€ for 6, 12, or 18 months, respectively) were significantly lower than that for major amputations (21,065€). Conclusions: A conservative approach appears more convenient than major amputations in ulcers not healing after 6 months, irrespective of the estimated risk of individual patients.

Retrospective Matched Case-Control Study on the Use of CO2 Laser for the Treatment of Nonhealing Diabetic Foot Ulcers: The DULCIS-2 (Diabetic ULcer, CO2 Laser, and Infections) Study.

PURPOSE: Infection, which is one of the possible complications of diabetic foot ulcers (DFUs), makes the treatment of ulcers challenging because of its negative impact on healing processes and the high prevalence of multiresistant germs. This study is aimed at verifying the effect of a surgical CO2 laser (which reduces the bacterial load and allows a more accurate debridement), as compared with the traditional lancets, on the healing rate of DFU. METHODS: The present case-control retrospective analysis was performed on patients with chronic (>6 months) DFU with Texas grade >1, treated with 80 W surgical CO2 laser (DEKA SmartXide2 C80, El.En. Group) and compared with a matched sample of patients with similar characteristics, who were treated with a traditional surgical approach. The debridement was performed trying to achieve the complete removal of nonviable tissues. The principal endpoint was the proportion of patients healed at 6 months. All analyses were carried out with SPSS 25.0. The study protocol was approved by the local ethical committee. RESULTS: This study included 118 patients (59 cases and 59 controls). At 6 months, the proportion of healing patients was 35% and 18% in cases and controls, respectively (P = .034). The corresponding figure at 1 year was 62% and 38% (P = .009), whereas no difference was observed at 1, 2, and 3 months. No serious adverse event was observed. CONCLUSIONS: In this article, we show for the first time that CO2 laser treatment, in comparison with traditional surgical approaches, can be associated with an increased healing rate in patients with DFU.

Effects of glucagon-like peptide-1 receptor agonists on mortality and cardiovascular events: A comprehensive meta-analysis of randomized controlled trials.

INTRODUCTION: The publication of the results of LEADER and SUSTAIN-6 trials suggested a possible beneficial effect of the class of GLP-1 receptor agonists on cardiovascular morbidity and mortality. The aim of the present meta-analysis is to collect and synthetize all available evidence on the effect of GLP-1 receptor agonists on cardiovascular events and mortality. METHODS: A Medline search for GLP-1 receptor agonists (exenatide, liraglutide, lixisenatide, albiglutide, dulaglutide, or semaglutide) was performed, collecting all randomized clinical trials with a duration >11weeks, enrolling patients with type 2 diabetes, and comparing a GLP-1 receptor agonist with placebo or any other non-GLP-1 receptor agonist drug. The principal outcome of this analysis was the effect of GLP-1 receptor agonists on all-cause and cardiovascular mortality, overall (fatal plus nonfatal) myocardial infarction, stroke, and heart failure. RESULTS: Out of 113 trials fulfilling inclusion criteria (mean duration 41.7±38.2weeks), 32, 25, 48, 43 and 32 reported at least one event for all-cause and cardiovascular mortality, overall (fatal plus nonfatal) myocardial infarction, stroke, and heart failure, respectively. In GLP-1 receptor agonist-treated patients, all-cause mortality, cardiovascular mortality, and myocardial infarction were significantly lower than in comparators (MH-OR [95% CI] 0.88 [0.79-0.97], p=0.015, 0.84 [0.74-0.96], p=0.009, and 0.90 [0.80-1.00], p=0.050, respectively), whereas no beneficial effect was observed for stroke and heart failure (MH-OR [95% CI] 0.90 [0.81-1.00]. p=0.059. 0.89 [0.76-1.04]. p=0.15. and 0.92 [0.81-1.06]. p=0.25. respectively). CONCLUSIONS: Overall, the agents of this class appear to reduce all-cause mortality, cardiovascular mortality, and the incidence of myocardial infarction at mid-term follow up.
