dCROX and ROX Indices Predict Clinical Outcomes in Patients with COVID-19 Pneumonia Treated with High-Flow Nasal Cannula Oxygen Therapy

Figure 3

The receiver operating characteristic (ROC) plot of dCROX and ROX indices for predicting successful weaning from high-flow nasal cannula therapy within 14 days. The best cutoff values of dCROX and ROX indices to predict HFNC weaning success within 14 days are 3.15 and 9.13, with the area under the ROC curve of 0.71 and 0.79, respectively.
