Fig. 3From: Exploiting an early warning Nomogram for predicting the risk of ICU admission in patients with COVID-19: a multi-center study in ChinaCalibration curves of the nomogram for predicting the risk of ICU admission in training (a) and validation cohort (b). Data on predicted and actual disease severity were plotted on the x- and y-axis, respectively. The diagonal dotted line indicates the ideal nomogram, in which actual and predicted probabilities are identical. The solid line indicates the actual nomogram, and a better fit to the dotted line indicates a better calibrationBack to article page
