[Correspondence] Overestimation of cardiovascular outcome incidence – Authors' reply

We thank Yuanzi Ye and Ricardo Fonseca for their interest in our Article.1 We agree that the cumulative incidence of each outcome is slightly overestimated when the simple technique for calculating Kaplan-Meier curves is used instead of a more sophisticated method accounting for competing risks. However, the effect of overestimation is modest and, because it affects all strata simultaneously, the hazard ratios (HRs) between strata are nearly unchanged.
