tients and updated meta-analyses. Methods: Centrally randomized, placebo controlled multicenter trial. All parties were blinded. Analyses were by intention to treat. Metaanalyses followed the Cochrane Collaboration methodology. Results: We randomized 4,372 patients with stable coronary heart disease to clarithromycin 500 mg (n = 2,172) or placebo (n = 2,200) once daily for 2 weeks. Mortality was followed through public register. Nine hundred and twentythree patients (21.1%) died. Six-year mortality was significantly higher in the clarithromycin group (hazard ratio 1.21, 95% confidence interval 1.06-1.38). Adjustment for entry characteristics (sex, age, prior myocardial infarction, center, and smoking) did not change the results (1.18, 1.04-1.35). Ad-
