Table 5 AUC, confidence interval, related inference, best threshold and related sensitivity and specificity for ROC curves about different CTSSs about diagnosis of severe/critical group at presentation and at peak disease severity and also for diagnosis of critical disease at peak severity

From: CT severity score in COVID-19 patients, assessment of performance in triage and outcome prediction: a comparative study of different methods
