Reclassification of renal function stages by the CG equation with respect to CKD-EPI equation, and effect of reclassification on mortality risk prediction.

Reclassification of renal function stages by the CG equation with respect to CKD-EPI equation, and effect of reclassification on mortality risk prediction.以CKD-EPI（慢性肾脏病流行病学合作研究，Chronic Kidney Disease Epidemiology Collaboration）方程为参照标准，采用CG（Cockcroft-Gault）方程对肾功能分期进行重新分类，并探讨该分期重新分类对死亡风险预测的影响。
