AKI prevalence and mortality across AKI stages and age categories in children with severe malaria. Bar graphs showing the frequency of AKI (a, c) or AKI mortality (b, d) using different approaches to estimate baseline serum creatinine (bSCr). b AKI severity was associated with increased mortality irrespective of method used to estimate bSCr (p < 0.0001 for all, Pearson’s Chi square test). c AKI prevalence differed across age categories when GFR based methods were used to estimate bSCr *p < 0.05. There was no difference in AKI prevalence when using approaches to directly estimate SCr (ns, p > 0.05). d AKI was associated with increased mortality across age categories
