Box and whisker plots showing the distribution of uAnCR (uAGT/creatinine ratio) by group in patients who developed AKI after cardiac surgery. (A) Among patients who had AKI of any AKIN stage at the time of sample collection (n = 97), uAnCR increased in a graded manner with AKI severity (as determined by maximum AKIN stage). (B) uAnCR increased in a graded manner with AKI (urinary Angiotensinogen and creatinine ratio) severity in the subset of patients who were classified as AKIN Stage 1 AKI at the time that their urine samples were collected (n = 79). Box plots show the median (solid line), 25th and 5th percentiles. Error bars represent the 5th and 9th percentiles. AKIN stage groups were compared with the Kruskal–Wallis test (P-value shown in bottom right). The asterisk represents a P < 0.05 compared with AKIN Stage 1 in the post hoc Dunn’s test for pairwise comparison. Figure adapted with permission from Alge et al. [23].
