In the univariate general linear models (GLM) with resistin as a dependent variable and CV risk degree as an independent variable, CV risk degree explained only 5.3% of the resistin variation in the CKD group and 12.1% of the resistin variation in patients with eGFR ≥ 60 mL/min/1.73 m2. This evidence concerns the gene RETN and chronic kidney disease.
