AGT and chronic kidney disease: Furthermore, when we performed ANOVA among CKD stage groups, the mean values of urinary AGT/Cr increased according to CKD stages (CKD stage I-II (n = 186), 27.8 ± 58.5 μg/g; CKD stage IIIA (n = 22), 56.0 ± 61.1 μg/g; CKD stage IIIB (n = 15), 89.0 ± 89.5 μg/g; CKD stage IV-V (n = 9), 95.3 ± 108.9 μg/g) (Fig. 2).
