Funnel plot for main operative outcomes (complications, conversions, and transfusions) among all studies that compared robotic surgery and laparoscopy.
(A) Publication bias regarding complications (Begg's test: Z = 0.48, p = 0.63; Egger's test: t = 1.03, p = 0.032). (B) Publication bias regarding conversions (Begg's test: Z = 1.22, p = 0.022; Egger's test: t = −1.64, p = 0.20). (C) Publication bias regarding transfusions (Begg's test: Z = 0.62, p = 0.54; Egger's test: t = 1.55, p = 0.17).
