Age band plus clinical factors sum to the ATRIA score; interpret using Singer 2010 risk bands.

How it works
The ATRIA stroke score was derived in a large anticoagulated atrial fibrillation cohort to refine ischemic stroke risk beyond age and prior stroke alone (Singer et al., Circulation 2010).
Limits
Derived in warfarin-era data; DOAC populations, imaging-defined events, and competing bleeding risk are not modeled here.
