Fig 2 ROCs for [I–E]O2 and Pe′co2 at the end of the weaning trial as predictors of the study endpoint within 24 h. The solid line ([I–E]O2) and dotted line (Pe′co2) show the sensitivity and specificity for each cut-off. The best cut-off was chosen as the value with the best combination of predictive power and specificity. Diagonal segments are produced by tie.
