Discrimination of the EPOS model in the development and validation cohorts for an ARAT cut-off at 10 and 32 points.
Fig 3.
Calibration plots for the external validation of the EPOS model for an ARAT cut-off at 10 points.
Analysis based on the imputed data. The model on day 5 was not externally validated in Cohort 2. The dotted line indicates perfect calibration, meaning that the predicted probabilities by the EPOS model (x-axis) and the observed probabilities in our sample (y-axis) are similar.

Analysis based on the imputed data. The model for day 5 was not externally validated in Cohort 2. ARAT, Action Research Arm Test.
