Box plots of serum CRP and albumin levels among those with and without AKI. A box represents interquartile range and a horizontal line in the box shows the median value. A bar shows range and outliers are shown in circles. P values were by Man-Whitney U test comparing values for those with and without AKI at each time point. The number of patients with available values was shown in tables below the graphs. CRP: C-reactive protein, AKI: acute kidney injury.
