1、摘要方程强(r=0.376)。各方程30%准确率比较差异均无统计学意义(P>0.05)。CKD-EPI(2012CysC/Cr)方程总分期准确性(P=0.604)高于其余各方程(P<0.05)。2在sGFR<60ml/min/1.73m的患者中,Hoek方程估测偏差绝对值中位数、估测偏差绝对值百分位数中位数均低于其它方程(P<0.001),Filler方程估测偏差中位数、估测偏差百分位数中位数均低于其它方程(P<0.001)。各方程eGFR与sGFR均高度相关(r>0.7)。Hoek方程30%准确率高于其余各方程(P<0.001),LeBricon方程总分期准确性高于其余各方程(P<0.0
2、01)。5.Bland-Altman作图法提示在总体CKD患者、不同性别CKD患者、各年2龄组CKD患者及sGFR<60ml/min/1.73m的患者中,Rule方程eGFR与sGFR2差值95%一致性界限最窄。而在sGFR≥60ml/min/1.73m的CKD患者中,Hoek方程eGFR与sGFR差值95%一致性界限最窄。结论:21.在年龄<75岁,sGFR<60ml/min/1.73m的南方汉族CKD患者中,Hoek方程在偏差、相关性、30%准确率、分期准确性及95%一致性限度等方面均优于(或不劣于)其它方程,可作为评估GFR的首选方程。22.在sGFR≥60ml/min/1.73m的
