This study investigated the relationship between cholesterol levels and stroke. The study included 38,053 subjects, aged 33 to 93 who were followed for three years.
The study found:
(a) Men who had the highest cholesterol levels, (218 mg/dL or 5.6 mmol/L), had a 9% reduced risk of stroke compared to men with the lowest cholesterol levels (167 mg/dL or 4.3 mmol/L).
(b) Women who had the highest cholesterol levels, (218 mg/dL or 5.6 mmol/L), had a 2% reduced risk of stroke compared to women with the lowest cholesterol levels (167 mg/dL or 4.3 mmol/L).
The study reveals that low cholesterol levels are associated with a higher risk of stroke.
