Figure 4 Curves of the predicted probabilities averaged across all patients and adjusted for previously determined baseline covariates. Curves show the relationships between creatine kinase (CK) ratio and adjusted probability of death or death and (re)myocardial infarction (MI) at six months. A and B refer to the entire study population, which is split according to ST-segment presentation on the admission electrocardiogram (ECG) in C and D. No statistically significant interaction with ECG strata was observed after correcting for the significant prognostic predictors.
