Evidence-based approach for intraabdominal drainage in pancreatic surgery: A systematic review and meta-analysis

Figure 2 Forest plot. A: Forest plot showing the association of clinically relevant postoperative pancreatic fistula (CR-POPF) incidence between the drain and no drain groups among patients who underwent pancreaticoduodenectomy (PD); B: Forest plot showing the association of CR-POPF between the drain and no drain groups among patients who underwent DP; C: Forest plot showing the association of delayed gastric emptying (DGE) between the drain and no drain groups among patients who underwent PD; D: Forest plot showing the association of DGE between the drain and no drain groups among patients who underwent DP; E: Forest plot showing the association of overall morbidity between the drain and no drain groups among patients who underwent PD; F: Forest plot showing the association of overall morbidity between the drain and no drain groups among patients who underwent DP; G: Forest plot shows the association of mortality between the drain and no drain groups among patients who underwent PD; H: Forest plot shows the association of mortality between the drain and no drain groups among patients who underwent DP. POPF: Postoperative pancreatic fistula; DGE: Delayed gastric emptying.
