BACKGROUND The US prevalence of reduced estimated glomerular filtration rate (eGFR) based on serum creatinine level increased during the decade ending in 2002. National Health and Nutrition Examination Survey (NHANES) cystatin C measurements recently were calibrated to the international standard, allowing for an independent test of the trend in prevalence of reduced eGFR using cystatin C level. STUDY DESIGN Cross-sectional surveys performed during 2 periods. SETTING & PARTICIPANTS… CONTINUE READING
