Stroke risks along the pFST.

<p>Line graphs showing stroke risk along a pFST of up to 15 years in patient populations representing (A) all combinations of risk factors, including 0–5 comorbidities, (B, C) presence or absence of prior stroke, and (D–F) age (categorized as <65, 65–75, or ≥75 years). Stroke risk is the probability of stroke occurring during the following year. Solid lines denote absence of prior stroke, and dashed lines denote presence of prior stroke. Green denotes age <65 years; blue denotes age 65–75 years; red denotes age ≥75 years. Note that 16 common CHA₂DS₂-VASc score-wise trajectories resulted.
