Normally distributed continuous variables are represented by the mean ± SE, non-normally distributed continuous variables are represented by the median (interquartile range), and categorical variables are represented by the number of cases and percentages. AP: Acute pancreatitis; BMI: Body mass index; ERCP: Endoscopic retrograde cholangiopancreatography; MAP: Mild acute pancreatitis; MSAP: Moderately severe acute pancreatitis; SAP: Severe acute pancreatitis.
