Achievement of therapeutic target: Odds Ratios (OR), 95% Confidence Intervals (CI), Success and Adverse Event Score in Endoscopic Retrograde Cholangiopancreatography (SASE). CI truncated at 8 (for better visibility), CI left of 1 shows significant results (negative / SASE 3 = low success), CI covering 1 shows non-significant results (n.s. / SASE 2), CI right of 1 shows significant results (positive / SASE 1 = high success)
