To ascertain the effect of the study ratios, including AST/ALT, ALP/ALT, and AST/ALP, on the likelihood of patient mortality, binomial logistic regression models, adjusted for age, gender, history of underlying disease (diabetes mellitus, hypertension, dyslipidemia, cardiovascular disease, atrial fibrillation), and smoking were performed. The gene discussed is GPT; the disease is atrial fibrillation.
