Figure 2. Correlation between the urine albumin-to-creatinine ratio (ACR) and the total urine protein-to-creatinine ratio (TPCR).
All of the axes are on a logarithmic scale. The regression expression was written as follows: ln ACR = 1.32×ln TPCR – 2.64 [coefficient of determination R2 = 0.861 (p<0.001)].
