The cumulative rate of cardiac end-points (cardiac death and non-fatal myocardial infarction) during a 5 year follow-up was 27.3/ 1000 in the gemfibrozil group (56 subjects) and 41.4/ 1000 in the placebo group (84 subjects) showing a relative risk reduction of 34.0% (95% confidence interval 8.2 to 52.6, p < 0.02) and an absolute risk reduction of 1.4% in the gemfibrozil group compared to placebo.
