Figure. Cluster Ranking of the 4 Surgical Strategies.

Cluster rank combined the surface under the cumulative ranking curve (SUCRA) values, success rate, and morbidity rate. The x-axis reports efficacy (success rate). The success of the procedure was defined as the clearance of the common bile duct according to the intention-to-treat analysis. The success rate was calculated as the ratio of patients in whom the assigned procedure was completed without protocol violations to the number of all randomized patients in each arm. The y-axis reports SUCRA values as a percentage of safety, defined as morbidity rate. The different colors represent different clusters. LC + IntraERCP indicates laparoscopic cholecystectomy (LC) plus intraoperative endoscopic retrograde cholangiopancreatography; LC + LCBDE, LC plus laparoscopic common bile duct exploration; LC + PostERCP, LC plus postoperative ERCP; and LC + PreERCP, LC plus preoperative ERCP.
