Fig. 3From: Flu-IV score: a predictive tool for assessing the risk of invasive mechanical ventilation in patients with influenza-related pneumoniaROCs for IMV prediction of four scorings in Flu-p patients from validation cohort. The AUROC value for the Flu-IV score model was 0.909, which was higher than that of the ROX index (AUROC = 0.594), modified ROX index (AUROC = 0.633) and HACOR scale (AUROC = 0.622)Back to article page
