ABSTRACT

This meta-analysis aimed to compare the effectiveness of metformin versus lifestyle interventions in preventing diabetes in individuals with prediabetes. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and conducted a comprehensive search of databases (PubMed, Cochrane Library, EMBASE) up to September 1, 2023. Five eligible studies were included. The results showed that there was no significant difference in the risk of developing diabetes between the metformin and lifestyle intervention groups (RR: 1.14, 95% CI: 0.77-1.68). Similarly, when comparing metformin with lifestyle intervention, the risk of diabetes was slightly higher in the metformin group, but this difference was not statistically significant (RR: 1.31, 95% CI: 0.93-1.86). When comparing metformin with lifestyle intervention to lifestyle intervention alone, no significant difference was observed in the incidence of diabetes (RR: 0.88, 95% CI: 0.74-1.04). In conclusion, our analysis found that the incidence of type 2 diabetes was slightly higher in patients receiving metformin alone compared to lifestyle intervention, but this difference did not reach statistical significance. Further trials are necessary to better evaluate these interventions for preventing type 2 diabetes in high-risk individuals.

ABSTRACT

Percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery are the options for revascularization in coronary artery disease (CAD). This meta-analysis aims to compare the efficacy of CABG and PCI for the management of patients with CAD. The meta-analysis was conducted as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. PubMed, Cochrane Library, and EMBASE were searched for relevant articles. The reference list of included articles was also searched manually for additional publications. Primary endpoints were cardiovascular mortality and all-cause mortality. Secondary endpoints included myocardial infarction, stroke, and revascularization. In total, 12 randomized control trials (RCTs) were included in this meta-analysis encompassing 9,941 patients (4,954 treated with CABG and 4,987 with PCI). The analysis showed that PCI was associated with a higher risk of all-cause mortality (risk ratio (RR) = 1.26, 95% confidence interval (CI) = 1.10-1.45) and revascularization (RR = 2.42, 95% CI = 1.82-3.21). However, no significant differences were reported between two arms regarding cardiovascular mortality (RR = 1.15, 95% CI = 0.96-1.39), myocardial infarction (RR = 1.17, 95% CI = 0.82-1.67), and stroke (RR = 0.64, 95% CI = 0.35-1.16). CABG was associated with a significant reduction in all-cause mortality and revascularization compared to PCI. However, no significant difference was reported in the risk of cardiovascular mortality, myocardial infarction, and stroke between the two groups.
