Data is presented as n (%) of patients who are not consistent with the non- OAC treatment recommendation by each decision aid. ARO: Always recommends OAC. AHA Aggressive: AHA guidelines (assuming that guideline recommends OAC at CHA2DS2-VASc = 1), AHA Conservative: AHA guidelines (assuming that guideline recommends non-OAC at CHA2DS2-VASc = 1), Casciano: Casciano tool, CHEST: CHEST guidelines, ESC: ESC guidelines, LaHaye: LaHaye tool.
