Figure 3 Observed versus predicted mortalities. Graphs A, C, and D represent predictions on the basis of troponin alone. Graph B represents predictions on the basis of troponin together with all predictor variables that remained significant in nested models. Points represent division of the data into groups of 10 predicted deaths. All 4 graphs use the combined data from both the derivation and validation sets. ACS = acute coronary syndrome; r/o = rule out.
