Receiver-operator characteristic (ROC) curves comparing the performances of the DIFE, the Logistic model and the estimated glomerular filtration rate (eGFR)-based conventional assessments in the validation cohort. (A) The DIFE compared with the Logistic Model. The area under ROC curve (AUC) for the DIFE equation was 0.70 (95% CI, 0.64–0.76), and the AUC for the Logistic Model was 0.60 (95% CI, 0.53–0.68). (B) The DIFE compared with the C-MDRD. The AUC for the C-MDRD equation was 0.55 (95% CI, 0.47–0.63). (C) The DIFE compared with the CKD-EPI. The AUC for the CKD-EPI was 0.53 (95% CI, 0.45–0.62). Abbreviations: DIFE, dialysis initiation based on the fuzzy mathematics equation; C-MDRD, Chinese modified Modification of Diet in Renal Disease equation; CKD-EPI, the Chronic Kidney Disease Epidemiology Collaboration equation.
