Figure 1. Observed (white columns) versus predicted (grey columns) probabilities of favorable outcome (FO) by prognostic quintile.

Figure 1

a. When all patients (DNAR and non-DNAR patients) are taken together, observed and predicted probabilities of FO agree well indicating a model with a good fit (goodness-of-fit p-value = 0.97). Number of patients is 85 per quintile (84 in quintile 5).

b, c. When patients are stratified by DNAR status, observed and predicted probabilities of FO no longer agree well indicating models with poor fit (for both, goodness-of-fit p-value < 0.001). Numbers of patients for quintiles 1-5 respectively are 12, 29, 49, 69, 82 for non-DNAR patients (b), and 73, 56, 36, 16, 2 for DNAR patients (c).
