Additional file 3: Figure S2. Algorithmic models of patients without ATN or proliferative glomerular disease (Non-ATN – Group 1/blue), with ATN (ATN – Group 2/red) and with glomerular proliferative lesion (PRO – Group 3/green). (A) Principal component analysis of groups of patients based in AKI diagnosis and cell numbers and types. (B) Binary tree model of groups of patients based in cell numbers and types. Transition of colors means the classification of groups accordingly as follows: blue - Non-ATN/Group 1; red – ATN/Group 2 and green – PRO/Group 3.
