Early vs late endoscopic retrograde cholangiopancreatography in patients with acute cholangitis: A nationwide analysis

Figure 2 Comparison of outcomes in patients hospitalized with cholangitis in early vs late endoscopic retrograde cholangiopancreatography stratified by cholangitis severity. Early endoscopic retrograde cholangiopancreatography (ERCP): Performed on the same day of admission or next day (days 0 or 1, < 48 h); Late ERCP: Performed on days 2 to 7 of admission (days 2-7, > 48 h after admission). Odds ratio for mortality outcomes was obtained from multivariable logistic regression controlling for age, sex, severe disease, and mortality score. Mortality score was replaced with readmission score for readmission outcomes. OR: Odds ratio; CI: Confidence interval; ERCP: Endoscopic retrograde cholangiopancreatography.
