Figure 1 Late actuarial survival after randomization to receive streptokinase or placebo after myocardial infarction. The log-rank comparison between the streptokinase and placebo groups was p = 0.022. At 5 years survival was 84% (95% confidence interval [CI] 76 to 90) in the streptokinase group and 70% (95% CI 60 to 77) in the placebo group (p = 0.023). At 12 years, survival was 66% (95% CI 55 to 75) in the streptokinase group and 51% (95% CI 41 to 60) in the placebo group (p = 0.022).
