Figure 1 Timing and duration of the first AKI episode. (a) Post-operative day of first evidence of acute kidney injury, defined as≥50% serum creatinine rise from baseline, on the x axis. The y axis depicts numbers of patients first attaining acute kidney injury on the given day. (b) Duration (days) of first acute kidney injury episode is displayed on the x axis. The y axis depicts the numbers of patients having a given duration of acute kidney injury.

Figure 2 Prediction of AKI using percentage serum creatinine rise from baseline as a predictor. Receiver operating characteristic (ROC) curve (sensitivity versus 1-specificity plot) showing percentage serum creatinine rise from baseline on post-operative day 1 (a) and post-operative day 2 (b) to predict a ≥50% SCr rise within 48h. AKI, acute kidney injury; POD, post-operative day, SCr, serum creatinine.
