highly significantp = 1.32E-09
When analysed within the largest of our cohorts (YFS) the minor allelic effect size of rs113288603 increased from non-significant ( beta = 0.05, p = 0.522) to highly significant ( beta = -0.47, p = 1.32E-09) when rs56113850 was added to the model; when an interaction term (rs56113850*rs113288603) was also added to the model the effect size further increased ( beta = -0.62, p = 1.32E-03).
