RI and histological damage scores. RI was correlated with glomerulosclerosis (GS), arteriolosclerosis (AS), and tubulointerstitial (TI) damage scores. The highest correlation was shown in TI lesions (𝑟=0.32, 𝑃<0.01 for the GS score; 𝑟=0.36, 𝑃<0.01 for the AS score; and 𝑟=0.43, 𝑃<0.01 for the TI score).
