Figure 2 Unadjusted hazard ratios and 95% confidence intervals for the risk of events 90 days after percutaneous coronary intervention by postprocedural cardiac troponin I (cTnI) status. Hazard ratios are depicted for the primary analysis population (n = 481) and for patients with negative preprocedural cTnI (n = 151). CK-MB = creatine kinase-MB; MI = myocardial infarction; SRI = severe recurrent ischemia.
