A new follow up study by Øjvind Lidegaard found that compared to combined oral contraceptives containing levonorgestrel users of vaginal ring contraceptives (such as NuvaRing) were 1.9 times more likely to suffer venous thrombosis. The VTE risk of vaginal ring users was 6.5 times higher than women not taking hormonal birth control.
The study also found an increase risk in transdermal patch birthcontrol as well, with women with 2.3 times more likely to have a VTE compared to users of combined oral contraceptives containing levonorgestrel and 7.9 times more likely than non users of hormonal contraceptives.
