The study population consisted of 1,031 Finnish men aged 46−65 years in the Kuopio Ischaemic Heart Disease Risk Factor cohort. Serum concentrations of carotenoids retinol and αtocopherol were measured by high-performance liquid chromatography. The association between the serum concentrations of lycopene α-carotene, β-carotene, α-tocopherol, and retinol and the risk of strokes was studied by using Cox proportional hazards models
