AIM The effects of dipeptidyl peptide-4 inhibitors (DPP-4is) and sodium-glucose cotransporter-2 inhibitors (SGLT-2is) on type 2 diabetes mellitus (T2DM) on cardiovascular events and all-cause mortality were compared. METHODS The literature on DPP-4is and SGLT-2is treatment of T2DM was searched through Pubmed, Embase, and the web of science databases with the search deadline May 15, 2020. Network meta-analysis (NMA) was used to compare the effects of two types of inhibitors on cardiovascular events (major adverse cardiovascular events (MACE), nonfatal myocardial infarction (MI), nonfatal stroke, and cardiovascular (CV) death) and all-cause mortality in T2DM patients. RESULTS A total of 15 articles were screened, including 125,796 patients. Compared with DPP-4is, SGLT-2is can significantly reduce MACE [OR: 0.86 95% CI (0.78, 0.92)], CV death [OR: 0.85 95% CI (0.71, 1.01)], nonfatal MI [OR: 0.84 95%CI (0.74, 0.95)] and all-cause mortality [OR: 0.78 95% CI (0.69, 0.89)]. For nonfatal stroke, DPP-4is and SGLT-2is have no statistically significant difference [OR: 0.99 95% CI (0.91, 1.07)]. CONCLUSION These data indicate that SGLT-2is is more beneficial to MACE and all-cause mortality in T2DM patients than DPP-4is.
