CKD stage, Chronic Kidney Disease stage; OR, odds ratio; VIF, variance inflation factor; Serum ALB level: <25 g/L is severe, 25–29 g/L is moderate, 30–35 g/L is mild. ALB, albumin.
The model assumption used here was binary logistic regress model. The co-linearity and interactions were analyzed by tolerance and VIF, respectively, there were no co-linearity and interactions.
