Fig. 2: Primary outcome.

Shown are the percentages of patients who had new-onset atrial fibrillation or atrioventricular conduction disturbance requiring the implantation of a permanent pacemaker in the colchicine group (n = 60 patients) and the placebo group (n = 60 patients) in the intention-to-treat analysis. The two-sided P value and the risk difference with 95% confidence intervals from the Mantel-Haenszel chi-square test for the comparison of the primary endpoint between the two treatment groups is shown. Data are presented as percentage of patients in which the primary endpoint occurred +/− the 95% confidence intervals (error bars). Source data are provided as a Source Data file.
