TBIL: total bilirubin; DBIL: direct bilirubin; ALB: serum albumin; WBC count: white blood cell count; Hb: serum hemoglobin; PLT: platelet count; PT/INR: prothrombin time and international normalized ratio; CREA: plasma creatinine; SE: standard error; RR: relative risk or risk ratio; value < 0.05 was considered significant.
