Endoscopic ultrasound-guided biliary drainage vs endoscopic retrograde cholangiopancreatography for malignant distal obstruction: Randomized-trial meta-analysis

Figure 2 Forest plot. A: Risk ratios use Paule-Mandel random effects and modified Hartung-Knapp confidence intervals; B: Clinical success according to each trial’s prespecified bilirubin-response definition; C: Procedure-related adverse events at the trial-reported early or 30-day window; D: Postprocedural pancreatitis. The plotted risk ratio uses a 0.5 continuity correction for zero cells; Peto and exact sensitivity estimates are reported in the text; E: Trial-defined stent dysfunction or reintervention. Definitions and follow-up horizons differed and are detailed in Supplementary Table 3.
