Cardiovascular outcome trials of anti-diabetic drugs according to the mean duration of the trial and relative risk reduction of major adverse cardiovascular events. The numbers in boxes are hazard ratios and 95% confidence intervals of major adverse cardiovascular events, defined as the composite of cardiovascular death, nonfatal myocardial infarction, and nonfatal stroke.
