The 30-day clinical endpoint was a composite of death from cardiovascular causes, recurrent myocardial infarction, or recurrent ischemia leading to the need for urgent revascularization. Odds ratios (OR) are adjusted for age, sex, region, hypertension, diabetes, infarct location, time to fibrinolytic therapy, and type of fibrinolytic. For each subgroup, the size of the box is proportional to the number of individuals included in the analysis. The horizontal lines represent the 95 percent confidence intervals (CI).
