Fig. 1From: Predictive accuracy of enhanced versions of the on-admission National Early Warning Score in estimating the risk of COVID-19 for unplanned admission to hospital: a retrospective development and validation studyReceiver Operating Characteristic curve for NEWS models (M0,M1,M2) and NEWS2 models (M0’,M1’,M2’) in predicting the risk of COVID-19 following admission in the validation dataset after correcting for calibration-in-the-large. Note: predicted probability at NEWS or NEWS2 threshold ≥ 5 (sensitivity, specificity) is shown for all modelsBack to article page
