AHSG and myocardial infarction: We find that genetically predicted fetuin-A reduces the risk of myocardial infarction in women (OR = 0.62, 95% CI 0.43–0.89, P =  < 0.01), but we do not find evidence for an association between genetically predicted fetuin-A and myocardial infarction in men (OR = 1.06, 95% CI 0.86–1.32, P = 0.56; P for interaction =  < 0.01; Fig. 2b, Online Table 7).
