Urinary SOD1 concentration by KDIGO AKI staging. Urinary concentrations of SOD1 were separated by stage of maximum AKI progression. The was a progressive increase in the mean urinary SOD1 concentrations with each stage of AKI: stage 1 (69.5 ng/ml ± 11.2 ng/ml, n = 158) VS stage 2: (132 ng/ml ± 92.1 ng/ml, n = 23) VS stage 3 AKI (986.8 ± 267.9 ng/ml, n = 20), * indicates significant difference from stage 1 AKI p < 0.0001 by one-way ANOVA
