Comparison of CKD prevalence estimates using different databases, equations, and definitions.
(A) GBD vs. NHANES (using the CKD-EPI2009 equation and fixed threshold). (B) CKD-EPI2009 vs. CKD-EPI2021 vs. EKFC (using the NHANES database and fixed threshold). (c) CKD-EPI2009 vs. CKD-EPI2021 vs. EKFC (using the NHANES database and age-adapted thresholds).
Table 3.
The estimated prevalence of low eGFR (eGFR < threshold(s)) among US adults in NHANES (2017-2018).
Table 4.
Number and weighted percentage of participants reclassified after applying age-adapted thresholds.
