This analysis indicates that while age and sex adjustment had only a minor effect on the odds ratio for Tregs and B cells, the effects on the CD4 Tconv and CD8 T‐cell subsets were larger, suggesting that the differences in conventional T‐cell subsets between the CAD+ and CAD− groups were likely because of the older age of the CAD+ group. This evidence concerns the gene CD4 and coronary artery disorder.
