Data available in 95 patients.
Provocative factors were not mutually exclusive. Fifteen of 98 women had more than one provocative factor: 13 women with 2 provocative factors each and 2 with 3 provocative factors each. In 12 women, VTE was provoked by the combination of oral contraceptive use/hormone treatment and another provocative factor.
Previous gynecological findings were not mutually exclusive. One woman had 2 gynecological findings (endometriosis and ovarian cyst).
