Forest plot of direct comparison meta-analysis of postoperative mortality rate between TF-TAVR versus TA-TAVR: a in-hospital mortality evaluated by M-H fixed-effect model; b 1-year mortality evaluated by M–H fixed-effect model; c mid-term mortality evaluated IV random-effects model. TF: transfemoral; TA: transapical; TAVR: transcatheter aortic valve replacement; OR, odds ratio; CI, confidence interval; H–M, Mantel–Haenszel; IV, inverse variance
