This study analyzed data from 55,000 people aged between 35 and 70 and estimated the effects on death rates of cholesterol levels decreasing from 240-259 mg/dL (6.24-6.73 mmol/l) to 160-179 mg/dL (4.2-4.6 mmol/l) by use of drug therapy.

The results show:
(a) In men, cholesterol levels falling from 240-259 mg/dL (6.24-6.73 mmol/l) to 160-179 mg/dL (4.2-4.6 mmol/l) would increase the death rate by 145%.
(b) In women, cholesterol levels falling from 240-259 mg/dL (6.24-6.73 mmol/l) to 160-179 mg/dL (4.2-4.6 mmol/l) would increase the death rate by 154%.
To conclude: The study showed that it is very clear that the lower your cholesterol is, the more likely you are to die. This was the same for all ages between 35 and 70, and for both sexes.
