Fig 3. Time-dependent receiver operating curve analysis to evaluate the predictive accuracy of each measurement day.

Fig 3

Results in the top right-hand corner of the figure indicate the integrated area under the curve (iAUC) and 95% confidence interval. The iAUC is a measure of the predictive accuracy for in-hospital mortality on each measurement day. The cholesterol level measured on postoperative day 7 had the highest iAUC.
