Table 2

Risks of rivaroxaban-associated major bleeding events compared to warfarin in selected studies.

	Risk of major bleeding (95% CI)	Risk of gastrointestinal bleeding (95% CI)	Risk of intracranial bleeding (95% CI)
Atrial fibrillation [3]	HR = 1.04; (0.9–1.2)	HR = 1.61; (1.30–1.99)	HR = 0.67; (0.34–0.93)
VTE [8]	HR = 0.49; (0.31–0.79)	RR = 0.56; (0.25–1.27)	RR = 0.10; (0.01–0.78)
