The correlation of the independent variables, including the numerical mean of the laboratory values of the WBC, Hb, AST2/ALT, aPTT, PT, and platelet count) and categorical data (NS1, ascites, gall bladder wall thickening/edema, and pleural effusion), with the dependent variables (platelet transfusion, bleeding, and length of hospital stay) formed the categorical data in the cross-tabulation (2 × 2), which were used to calculate the odds ratio. Here, GPT is linked to Pleural effusion.
