^aThirty-eight percent of the patients had acute kidney injury (AKI), and sixty-two percent were classified as Kidney Disease: Improving Global Outcomes (KDIGO) stage 0. Numbers and ratios of patients separated into each KDIGO stage are displayed. The KDIGO stage was determined on the basis of the creatinine or diuresis criterion. Eight patients were defined as patients with AKI primarily on the basis of increased serum creatinine concentration, and eight patients first reached the threshold of a low diuresis rate.
