Figure 3 Funnel plot. A: Funnel plot of clinically relevant postoperative pancreatic fistula (CR-POPF) between the drain and no-drain groups among patients who underwent pancreaticoduodenectomy (PD). Egger test result: T = 0.31, df = 10, P value = 0.7657; B: Funnel plot of CR-POPF between the drain and no-drain groups among patients who underwent DP; C: Funnel plot of delayed gastric emptying between the drain and no drain groups among patients who underwent PD; D: Funnel plot of overall morbidity between the drain and no drain groups among patients who underwent PD; E: Funnel plot of mortality between the drain and no-drain groups among those who have undergone PD.
