Student’s -test for continuous variables and Pearson’s chi-square test for categorical variables. The multivariate logistic regression model included variables which are confirmed to be statistically significant by univariate analysis as independent variables and PAD as dependent variable. CBD: common bile duct; ERCP: endoscopic retrograde cholangiopancreatography.
