Funnel plot of primary outcomes included in the meta-analysis. The funnel plot of (a: 3-year MACE, b: 3-year MI, c: 3-year death, d: 3-year ST, e: 4-year MACE, f: 4-year MI, g: 5-year ST). the standard error (SE) of the ln relative risk (RR) was plotted against the relative risk for (a:3-year MACE, b: 3-year MI, c: 3-year death, d: 3-year ST, e: 4-year MACE, f: 4-year MI, g: 5-year ST) 3-year MACE. The absence of any asymmetric distribution suggested no publication bias
