CRP and diabetes mellitus: To identify independent associations between uremic toxins and lipid profile, we performed multivariate linear regression analyses with adjustment for age, sex, cohort, body mass index (BMI), presence of diabetes, high sensitivity C-reactive protein (hsCRP), statin use, estimated glomerular filtration rate (eGFR), and dialysis treatment only for those parameters that were significantly correlated to lipid markers in univariate analyses.
