BUN: blood urea nitrogen, PT: prothrombin time, K: serum potassium, Na: serum sodium, TBIL: total bilirubin, ALT: alanine aminotransferase, AST: aspartate aminotransferase, ALP: alkaline phosphatase, GGT: γ-glutamyl transferase, WBC: white blood cell. PF: physical function, RP: physical roles, BP: bodily pain, GH: general health, VT: vitality, SF: social roles, RE: emotional roles, MH: mental health, PCS: physical component summary, MCS: mental component summary, SF-36: 36-item short form. Only data with 𝑃<0.05 were expressed as values of beta-coefficients. “—”: 𝑃>0.05.
