- Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the Number of Decision Aid Diagrams [ Time Frame: after seeing the decision aid (5 min) ]after regarding the risk diagram, the physician will decide to prescribe/take or not the treatment
- Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the Timeframe for Risk Presentation (1 vs 5 Years) [ Time Frame: 5 minutes ]the proportion of physicians deciding to prescribe OAC after seeing risk estimation on 1 vs 5 years
- Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the Target of Prescription (Patient vs. Physician Himself) [ Time Frame: 5 min ]the participant physicians were randomized to prescribe to virtual patients or to imagine that the risk seen in the diagram was that of themselves
- Number of Participants Who Prescribed Oral Anticoagulants (OAC) According to the CHA2D2s-VASC Risk Score [ Time Frame: 5 min ]The proportion of OAC prescription for the range 1-5 of CHA2D2s-VASC scores. CHA2D2S-VASC risk score ranges from 1-5, with higher scores indicating a greater risk of stroke.
