Calibration plots for logistic regression models. The red line refers to the reference slope or perfect calibration. The blue line refers to actual calibration slope of the model of interest. The dots refer to the observed frequency of events per tenth of predicted risk. (A) Unadjusted model for in-hospital mortality. (B) Unadjusted model for long hospital length of stay. (C) Unadjusted model for 30-day emergency hospital readmissions. (D) Adjusted model for in-hospital mortality. (E) Adjusted model for long hospital length of stay. (F) Adjusted model for 30-day emergency hospital readmissions.
