Distribution of blood urea nitrogen (BUN), plasma creatinine values according to AKI groups. The box extends from the 25th to 75th percentiles. The line in the middle of the box is plotted at the median and whiskers delimit min to max values. a - BUN values at admission of patients with prerenal (PR AKI) and intrinsic AKI (I AKI); (b) - Plasma creatinine values at admission of patients with PR AKI and I AKI; (c) - Lowest plasma creatinine during the 7 days following admission (Adm.) of patients with PR AKI and I AKI
