I would really recommend this site for people who are looking for data on statins and alternatives.
thennt.com/nnt/statins-for-...
The idea of the site is that it is NOT commercially sponsored in any way, and tries to give the public unbiased medical information. As you can see from the information for statins for primary prevention, some people will benefit from statins, but an equal number will suffer disbenefits such as developing diabetes.
It also has this very helpful section on cardiac interventions that do work.
