Mean predicted probability versus the observed event rate over 10 predicted probability groups between 0 and 1 at an increment of 0.1 for the scenario without hospital use for COVID-19 as predictors. The black line at 45 degree represents a line of perfect calibration. The grey lines are the linear regression lines for modelling the observed event rate against the mean predicted probabilities over the 10 groups as predictor
