FIGURE 2.
Forest plot and meta-analysis of the occurrence rate of complications. The occurrence rate was similar in ECP and non-ECP (WMD = 1.03, 95% CI: 0.67–1.58, P = 0.91). CI = confidence interval, ECP = endoscopic cyclophotocoagulation, M-H = Mantel–Haenszel method, non-ECP = non-endoscopic cyclophotocoagulation (alternative surgeries).
