Endometriosis and long-term risk of venous thromboembolism: a Danish nationwide study.

The study included 63 999 women with endometriosis and 255 996 matched female controls.

At baseline, women with endometriosis had a higher burden of comorbidities, had greater use of medications, and more often had a history of abdominal/gynaecological surgeries.

The incidence rate of venous thromboembolism was higher in women with endometriosis [2.18 per 1000 person-years; 95% confidence interval (CI) 2.10-2.26] compared with controls (1.54 per 1000 person-years; 95% CI 1.51-1.58).
