Prognostic value of glomerular-filtration-rate estimated by common and modified Asian/Chinese equations for cardiovascular outcomes in elderly Chinese individuals

Figure 1 Flow chart of the screening process for the study population from the Northern Shanghai Study.

Figure 2 Kaplan-Meier curves show the relationship between estimated glomerular filtration rate and survival free from major cardiovascular events. eGFR: Estimated glomerular filtration rate; MDRD: Modification of Diet in Renal Disease; c-aMDRD: Chinese-abbreviated Modification of Diet in Renal Disease; CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration; aCKD-EPI: Asian-adapted Chronic Kidney Disease Epidemiology Collaboration; cCKD-EPI: Chinese-adapted Chronic Kidney Disease Epidemiology Collaboration; MACE: Major adverse cardiovascular events.

Figure 3 Prediction of major cardiovascular events by estimated glomerular filtration rate calculated using different equations. eGFR: Estimated glomerular filtration rate; MDRD: Modification of Diet in Renal Disease; c-aMDRD: Chinese-abbreviated Modification of Diet in Renal Disease; CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration; aCKD-EPI: Asian-adapted Chronic Kidney Disease Epidemiology Collaboration; cCKD-EPI: Chinese-adapted Chronic Kidney Disease Epidemiology Collaboration; HR: Hazard ratio; CI: Confidence interval.

Figure 4 Comparison of predictive ability of different estimated glomerular filtration rate equations. A: Compared to the Modification of Diet in Renal Disease equation; B: Compared to the Chinese-abbreviated Modification of Diet in Renal Disease equation. AUC: Area under of the receiver operating characteristic curves; MACE: Major adverse cardiovascular events; MDRD: Modification of Diet in Renal Disease; c-aMDRD: Chinese-abbreviated Modification of Diet in Renal Disease; CKDEPI: Chronic Kidney Disease Epidemiology Collaboration; aCKDEPI: Asian-adapted Chronic Kidney Disease Epidemiology Collaboration; cCKDEPI: Chinese-adapted Chronic Kidney Disease Epidemiology Collaboration.
