aPatients within the Hokusai-VTE trial received Edoxaban 30 mg daily if CrCl 30–50 ml/min, body weight ≤60 kg, or receiving concomitant treatment with potent P-glycoprotein inhibitors. Comparison completed against only those warfarin patients with same characteristics
bSubgroup of male patients within the Hokusai-VTE trial had statistically reduced bleeding outcomes than women, favoring edoxaban (6.1% edoxaban vs. 9.1% warfarin in males, and 11.7% edoxaban vs. 11.8% warfarin in females; p value for interaction of 0.0041) but no difference in efficacy. Subgroup of patients with INR percent time in therapeutic range <60% also derived statistically better reductions in primary safety outcome with edoxaban (6.9% edoxaban vs. 10.9% warfarin) compared to patients with ≥60% time in therapeutic range (9.2% edoxaban vs. 10% warfarin); p value for interaction of 0.0175
