title: Risk of idiopathic venous thromboembolism in users of progestagens alone.
abstract: Overall, there was a modest, non-significant, positive association between exposure to progestagens alone and venous thromboembolism (VTE). There was no effect with progestagens alone used for contraception, whereas there was a substantial association with the higher dose progestagens used for other reasons.
