In the AFib stroke risk scoring model, which age category contributes one point?

Explanation:
In the AFib stroke risk scoring model (CHADS-VASc), age adds points in two brackets: 65–74 years gives 1 point, and 75 years or older gives 2 points. Younger than 65 adds 0 points from age alone. So the category that contributes one point is 65–74 years. This reflects a moderate increase in stroke risk with advancing age, while the risk jumps more after 75, hence the higher 2-point contribution for that older group. The total score also includes other factors like heart failure, hypertension, diabetes, prior stroke/TIA, vascular disease, and sex, which together guide anticoagulation decisions.
