1, 2, 3 uPCR denote first, second, and third uPCR, respectively. 1.2uPCR, 2.3uPCR, 1,3uPCR each denote the sum of the two indicated uPCRs. 1.2.3uPCR denotes the sum of the three uPCRs. 1, 2, 3uACR denotes first, second, and third uACR, respectively

uACR, urinary albumin-to-creatinine ratio; uPCR, urinary protein-to-creatinine ratio, CO(YI), cut-off value using Youden's index by the receiver operating characteristics curve
