*Three hundred and thirty-one observations (out of 490 charts, after excluding charts with missing info on airway errors, gender, and scene time and excluding outliers); likelihood-based pseudo R2=0.12 maximum-rescaled R2=0.26.
†Four outliers with a standardised deviance residual of >2.50 were removed from the final model.
