External validation of NEWS2 models (M0’, M1’, M2’) for predicting the risk of COVID-19. NB: We limit the risk of COVID-19 to 0.30 for visualisation purposes because beyond this point, we have few patients. The grey solid line shows ideal calibration. The black solid line shows the observed calibration along with 95 % confidence intervals in black dashed lines
