Difference (Δ) in estimated prevalence of stage 3 or 4 chronic kidney disease (CKD) using the age, sex, race, and cystatin C level estimated glomerular filtration rate (eGFRCysC,age,sex,race) and Modification of Diet in Renal Disease (MDRD) Study (eGFRMDRD) equations by body mass index (BMI) for demographic subgroups. White columns, eGFRMDRD estimate; black columns, eGFRCysC,age,sex,race estimate. BMI categories: 1, normal weight (18.5 to 24.9 kg/m2); 2, overweight (25.0 to 29.9 kg/m2); and 3, obese (≥30 kg/m2). ΔCKD prevalence was calculated as eGFRCysC,age,sex,race estimate − eGFRMDRD estimate.
