The study investigated various factors that are associated with the risk of stroke. The study included 2,302 subjects aged 40 years or older who were followed for 15.5 years.
Regarding cholesterol levels, the study found:
(a) In men, every 1.21 mmolL (46.7 mg/dL) increase in cholesterol levels was associated with a 13% decreased risk of stroke.
(b) In women, every 1.21 mmolL (46.7 mg/dL) increase in cholesterol levels was associated with a 1% decreased risk of stroke.
The data from the study indicates that higher cholesterol levels are associated with a decreased risk of stroke.
