  • Description: <jats:title>Abstract</jats:title> <jats:sec> <jats:title>BACKGROUND AND AIMS</jats:title> <jats:p>Current Glomerular filtration rate (GFR) estimating equations based on serum creatinine are facing increased criticism due to the inclusion of a race correction in black Americans with the CKD-EPI equation (CKD-EPIASR, A = Age, S = Sex, R = Race). A new equation without race (CKD-EPIAS) has been proposed. However, this equation was developed mainly from US cohorts. The performance of this new equation has been poorly compared with current European-developed creatinine-based equations, i.e. the Lund-Malmö Revised (LMR), and the new European Kidney Function Consortium (EKFC)</jats:p> </jats:sec> <jats:sec> <jats:title>METHOD</jats:title> <jats:p>Data from subjects over 18 years, representing 11 cohorts from Europe (previously described as the EKFC dataset, n = 13 856), and enhanced with data from Brazil (n = 100), France (n = 4429) and Africa [Democratic Republic of Congo (DRC) and Côte d'Ivoire, n = 508] were considered (n = 18 893 for the whole cohort). The EKFC cohort was considered as non-black population. All data from Africa derived from black individuals. From France, 964 subjects were self-reported as black (=Blacks from Paris). Measured GFR as a reference method and IDMS creatinine results were available. Median bias (eGFR—mGFR) with 95% confidence intervals (CI), imprecision (interquartile range: IQR), and P30 accuracy (percentage of eGFR-values within ± 30% of mGFR) with 95% CI were calculated.</jats:p> </jats:sec> <jats:sec> <jats:title>RESULTS</jats:title> <jats:p>Results are summarized in Table.</jats:p> </jats:sec> <jats:sec> <jats:title>CONCLUSION</jats:title> <jats:p>The new CKD-EPIAS has been launched in the USA for societal reasons and is now recommended by US guidelines. However, in Europe and Africa, its performance was suboptimal. The EKFC equation, using the usual Q values, or population-specific Q values (when available), displays the best performance over the whole age range for populations in Europe and Africa.</jats:p> </jats:sec>
