APOE and myocardial ischemia: Here, we made use of a large population-based study of people of mean age 56.9 years, i.e., the UK Biobank, with high-quality indicators of potential population stratification, to assess effects of common APOE genotypes on IHD overall, stratified by age at recruitment to obtain estimates less open to selection bias, and by sex to provide insights about differences by sex.
