Blackwater fever and severe AKI in children with an acute febrile illness. Heat map of standardized biomarker levels with the mean in each group plotted and differences between groups analyzed using linear regression models. Biomarkers are the dependent variable and severe AKI (sAKI) and blackwater fever (BWF) are predictor variables, with an interaction term, where *p < 0.05, **p < 0.01, ***p < 0.001
