  • Note: ICER = incremental cost-effectiveness ratio, QALY = quality-adjusted life year.

  • * In 2018 Canadian dollars.

  • Warfarin is dominated by extension by the combination of acetylsalicylic acid and apixaban, whereas edoxaban, rivaroxaban and dabigatran are absolutely dominated by apixaban.
