Additionally, the HR in the high-risk group was 3.21 (95% CI 2.07–4.98) compared to the low-risk group after adjusting for AF, HB, TLB, Alb, T3, T4, PT, anticoagulant, and direct bilirubin (Table 4), that means the high-risk group exhibiting a 3.21-fold increased hazard of mortality compared to the low-risk group. The gene discussed is ALB; the disease is atrial fibrillation.
