Figure 4. Hazard risk of adverse events according to IHD history and troponin status. Subgroup analysis is shown with hazard ratios and 95% confidence intervals (CI) for adverse events (composite endpoint including cardiac death and nonfatal MI; all-cause death) among subgroups of patients (with IHD history vs. without IHD history) according troponin status (negative vs. positive). The probability value for interaction represents the likelihood of interaction between the variables. IHD: ischemic heart disease.
