Fig. 5From: Influence of sugammadex versus neostigmine for neuromuscular block reversal on the incidence of postoperative pulmonary complications: a meta-analysis of randomized controlled trialsFunnel plots for the meta-analysis comparing the incidence of PPCs after the use of sugammadex and neostigmine for NMB reversal. Each square represents one of the included studies, and the plots were formed based on the data of OR (x-axis) and standard error of lg(OR) (y-axis). A symmetrical of the plots could be indicated if the distributions of the squares were symmetrical according to the vertical line as the axisBack to article page
