From: Practical clinical and radiological models to diagnose COVID-19 based on a multicentric teleradiological emergency chest CT cohort

Figure 6

Decision curve analysis (DCA) of the final models and conclusions of the on-call teleradiologists (OCTRs) in the validation cohort, depending on data on which they were trained: (a) radiological and (b) clinical + radiological. The x-axis corresponds to the odds or risk threshold at which a patient would opt for COVID-19 management. The y-axis corresponds to the overall net benefit. The black line represents the ‘treat all’ patients COVID-19 strategy. The grey horizontal line represents the ‘treat none’ of the patients strategy. For both sources of data, the added value of the models over the ‘treat all’ strategy and the OCTRs readings are highlighted for risk thresholds above 0.43 (arrows). CART classification and regression tree, Step-LR stepwise logistic regression.
