Figure 1

Comparison of age-adjusted prevalence of CKD with estimation of the GFR by the MDRD Study equation and the CKD-EPI equation, stratified by hypertension or hyperglycemic status. CKD prevalence expressed as mean ± SD. All P values less than 0.05 for ANOVA tests across all four groups. HTN refers to the self-reported patients, those with the use of antihypertensive drugs, or detected with undiagnosed hypertension; DM refers to self-reported type 2 diabetes or elevated FPG (FPG ≥ 100 mg/dL). Abbreviations: MDRD Modification of diet in renal disease, CKD-EPI Chronic kidney disease epidemiology collaboration, FPG Fasting plasma glucose, HTN Hypertension.
