eGFRscr, glomerular filtration rate estimated based on the serum creatinine level using the Chronic Kidney Disease Epidemiology Collaboration equation; CKD, chronic kidney disease; IQR, inter-quartile range.
aThe Chi-square test for categorical variables; t-test for age and eGFRscr; the Wilcoxon test for BTP.
bAlbuminuria defined as urinary albumin creatinine ratio >30.
cCKD defined as eGFRscr <60 mL/min/1.73 m2 or the presence of albuminuria.
