2. Figure 1
Calibration curve for model. Observed vs predicted probability of an early readmission in the derivation and validation cohorts. The diagonal line would be a perfect fit. For early readmission the Hosmer–Lemeshow goodness-of-fit test statistic is 0.36 for the derivation cohort and 0.50 for the validation cohort.
