To the Editor We read with interest the article by Jena et al,1 and we commend them for their thoughtful analyses. Many readers will undoubtedly cite decreased mortality during cardiovascular meetings as the study’s key finding, but we favor a more conservative conclusion. The investigators set out to test the reasonable hypothesis that mortality would increase during meetings. For this reason, we believe a 1-sided statistical test would have been more appropriate for the primary analysis rather than the 2-sided test employed.2 By negating their primary hypothesis, the authors showed that mortality did not increase during meetings, which we view as the study’s key finding.
