Table 3 Disease activity and venous thromboembolism risk

Ref.	Findings	Statistics
Grainge et al[3]	IBD flares are associated with increased risk of developing VTE as compared to non-IBD matched controls	Hazard ratio 8.40 (95%CI: 5.50-12.80)
Hansen et al[29]	IBD flare during pregnancy is associated with increased risk of developing VTE as compared to non-IBD pregnant patients (also compared to IBD pregnant patients without a flare)	Unadjusted relative risk 2.64 (95%CI: 1.69-4.14)
Bollen et al[32]	A significant proportion of patients had active disease at the time of VTE diagnosis	60/84 (71%) patients with VTE had active disease

VTE: Venous thromboembolism; IBD: Inflammatory bowel disease.
