Patients with pre-operative albumin at 5 mg/dL (blue line), 4mg/dL (green line), 3.5mg/dL (black line), 3mg/dL (orange line), and 2.5mg/dL (red line) were shown in the graph. Survival probability at day t ; S(t)=exp(-λt), Moment mortality: λ=exp(−8.22281–0.106462×Alb). The survival probability of a patient with albumin 3.0 mg/dL at day 2000 showing S(2000)=82.3%, a patient with albumin 2.5 mg/dL at day 2000 showing S(2000)=66.3%, and a patients with albumin 4.5 mg/dL at day 2000 showing S(2000)=71.7%.
