Hospitalized ulcerative colitis patients have an elevated risk of thromboembolic events

Table 2 Estimated population percentages of non-surgical discharges which had thromboembolic events and comparison of event rates

Thromboembolic event	Ulcerative colitis vs diverticulitis		Ulcerative colitis vs respiratory failure
	Rate difference, % (95% CI)	P value	Rate difference, % (95% CI)	P value
Deep venous thrombosis	1.05 (1.69 to 0.41)	0.01	0.48 (-0.18 to 1.14)	0.2
Pulmonary embolism	0.31 (0.03 to 0.59)	0.03	-0.56 (-0.92 to -0.2)	0.002
Venous thrombo-embolism	1.26 (0.56 to 1.97)	0.004	0.04 (-0.72 to 0.8)	0.9
Stroke	0.03 (-0.28 to 0.34)	0.9	-1.11 (-1.52 to -0.7)	< 0.001
Arterial thrombo-embolism	0.01 (-0.21 to 0.24)	0.9	-0.33 (-0.59 to -0.08)	0.01
