Values presented as mean ± SD or n (%). P values: 1^st column reflects comparison of IOF to MOF, and 2^nd column reflects comparison of IOF to no OF. IOF: Isolated organ failure; MOF: Multiple organ failure; OF: Organ failure; AP: Acute pancreatitis; BMI: Body mass index; IQR: Interquartile range; ERCP: Endoscopic retrograde cholangiopancreatography.
