However, after adding in variables with previously reported associations with RANTES (i.e., CKD, serum creatinine, BMI, and metabolic syndrome), only younger age (β = −0.043; 95% CI: −0.08, −0.007) and female sex (β = 0.212; 95% CI: 0.109, 0.314) remained significant (Model 1.3). This evidence concerns the gene CCL5 and chronic kidney disease.
