Stroke Rates: 1980-2000: The Minnesota Stroke Survey
Key result
From 1980 to 2000, clinically defined stroke rates remained stable for women and declined modestly for men, while 28-day stroke survival improved by 16% for women and 12% for men.

Implication
Improved survival may reflect care advances or milder cases; leaves open whether stable rates persist amid modern imaging and prevention.

Outcome
Age-adjusted, sex-specific hospitalized stroke attack rates and short-term (28-day) stroke survivalhard clinical
Short-term stroke survival improved significantly from 1980 to 2000 despite stable clinically defined stroke rates, which may reflect treatment advances or the ascertainment of less severe strokes due to increased neuroimaging.
Limitations
- Improved short-term survival may imply ascertainment of less severe strokes, possibly masking a true decline in stroke rates.
