Abbreviations: MI, myocardial infarction; OR, odds ratio; CI, confidence interval; VTE, venous thromboembolism; DVT, deep vein thrombosis.

^aHistory of MI among parents, brothers, sisters, or offspring, or any combination thereof.

^bStatistical significance of P for interaction corresponds to level ≤ .05.

^cOdds ratios reflect the influence of a family history of MI and are adjusted for education using conditional logistic regression.

^dData are given as number of participants (percentage with a family history of MI in any relative).

^eP < .01.

^fP < .05.
