APOA5 and chronic kidney disease: Stratified analyses of the CKD risk for the APOA5 T − 1131C (rs662799) SNP by BMI resulted in a strikingly higher OR for individuals with at least one C allele of APOA5 T − 1131C (rs662799) when only those individuals with BMI ≥30 were included (OR 12.39 (95% CI: 1.55–99.09); Table 3).
