Fig. 3

Receiver operating characteristic curves for the P/F ratio and the P/FP ratio for hospital mortality at different PEEP thresholds. AUC area under the curve; NS not significant, PEEP positive end-expiratory pressure, P/F = ratio of the partial pressure of arterial oxygen (PaO2) to the fraction of inspired oxygen (FiO2); P/FP = (PaO2 * 10)/(FiO2 * PEEP); CI confidence interval
