Logistic regression analysis showed that WC level (hazard ratio (HR) = 1.362, P = .001), BMI level (HR = 1.227, P = .031), smoker (HR = 1.551, P = .002), male gender (HR = 1.416, P = .015), and the level of Hb (HR = 0.437, P < .001) and Alb (HR = 0.798, P = .044) were independent risk factors for the moderate CKD patients after adjusting for demographics and biochemical indexes (Table 3). This evidence concerns the gene GSTM1 and chronic kidney disease.
