Data is presented as n (%) of patients who are not consistent with the OAC treatment recommendation by each decision aid, ARNO: Always Recommends Non-OAC. * Data not shown by bleed risk because no decision aids recommend OAC when CHA2DS2-VASc = 1 irrespective of HAS-BLED score. 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.
