Forest plot of direct comparison meta-analysis of postoperative event rate between TF-TAVR versus TA-TAVR: a major vascular complication evaluated by IV random-effect model; b pacemaker implantation evaluated by M–H fixed-effect model; c major bleeding by IV random-effect model. TF: transfemoral; TA: transapical; TAVR: transcatheter aortic valve. d acute kidney injury evaluated by IV random-effect model; e length of hospital stay evaluated by IV random-effect model; f stroke evaluated by M–H fixed-effect model. TF: transfemoral; TA: transapical; TAVR: transcatheter aortic valve replacement; OR, odds ratio; CI, confidence interval; H–M, Mantel–Haenszel; IV, inverse variance
