• W3211537701 abstract "Abstract Objective To assess the clinical practicability of the ensemble learning model established by Liu et al. in estimating glomerular filtration rate (GFR) and validate whether it is a better model than the Asian modified Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation in a cohort of Chinese chronic kidney disease (CKD) patients in an external validation study. Methods According to the ensemble learning model and the Asian modified CKD-EPI equation, we calculated estimated GFR ensemble and GFR CKD-EPI , separately. Diagnostic performance of the two models was assessed and compared by correlation coefficient, regression equation, Bland–Altman analysis, bias, precision and P 30 under the premise of 99m Tc-diethylenetriaminepentaacetic acid ( 99m Tc-DTPA) dual plasma sample clearance method as reference method for GFR measurement (mGFR). Results A total of 158 Chinese CKD patients were included in our external validation study. The GFR ensemble was highly related with mGFR, with the correlation coefficient of 0.94. However, regression equation of GFR ensemble = 0.66*mGFR + 23.05, the regression coefficient was far away from one, and the intercept was wide. Compared with the Asian modified CKD-EPI equation, the diagnostic performance of the ensemble learning model also demonstrated a wider 95% limit of agreement in Bland-Altman analysis (52.6 vs 42.4 ml/min/1.73 m 2 ), a poorer bias (8.0 vs 1.0 ml/min/1.73 m 2 , P = 0.02), an inferior precision (18.4 vs 12.7 ml/min/1.73 m 2 , P < 0.001) and a lower P 30 (58.9% vs 74.1%, P < 0.001). Conclusions Our study showed that the ensemble learning model cannot replace the Asian modified CKD-EPI equation for the first choice for GFR estimation in overall Chinese CKD patients." @default.
