Figure 2. Model performance by ICH Score.

Figure 2

This model was generated in 300 patients in whom the ICH Score (1) could be calculated, irrespective of DNAR orders. Model performance is shown, stratified by DNAR status, and shows disparities between observed (white columns) and predicted (grey columns) probability of favorable outcome (FO) indicating models with poor fit (for both, goodness-of-fit p-value < 0.001). Numbers of patients for ICH scores 0-4 respectively are 58, 60, 32, 15, 4 for non-DNAR patients (a), and 2, 18, 25, 58, 24 for DNAR patients (b). Because only 4 patients had ICH Score 5, all of whom had a poor outcome, these were not included in logistic model or figures.
