Do people find it worrying that 34% of people on lipid lowering therapy have a "normal" lipid profile
http://www.totallipids.com/total_lipids/totallipids/cv_risk/index.jsp
What can be read into a trial where everybody had "normal" cholesterol levels, everybody was giver some lipid loweing drug, yet there was still 1 cardivascular event for every 12 people.

Surely if cholesterol was the cause of heart disease we would expect much fewer cardiovascular events in a group of people without high cholesterol, and still getting cholesterol lowering drugs?

Someone actually had a look at the links and thought about it. You are correct about the people with normal lipid levels being a result of the drugs efficacy. But the question remains, why are they still on the drugs?
The answer of couse is they need them to keep their cholesterol levels low. Whatever caused high cholesterol in the first place is still there, while a person is committed to a lifetime of medications that merely mask the so called problem . Isn't the health system just wonderful? ,
As for the study i linked to, if you read it carefully every patient was on atorvastatin, in the study one group was "randomly assigned additional atorvastatin ". Some people just recieved more than others. The only thing we can glean from the numbers given is that those who recieved the extra dose, ended up with a total serum cholesterol 1.2mml lower, with a baseline of 6.5 , Thats a reduction of 18% Quite a large reduction in fact

Yet it is claimed there is a large reduction in major cardivascular events
Lets have a look at the figures.
7.5% (389 out of approx 5152) in the extra dose group had a cardiovascular event
9.5 % (486 out of arrox 5152) in the control Thats a difference of 2.2% (asolute risk, as opposed to relative risk)
Now the absolut difference in the level of cholesterol will be probably be just under 18%.
If reducing cholesterol was what gave protection, then we would expext a correlation between level of reduction and protection offered. This is not the case. What little protection these drugs give is not due to their lipid lowering ability.
Its intersting that you accuse me of using half baked evidence for what was merley an attempt to promote thought, while many people dutifully swallow all the fully baked evidence, with even more minions blindly believing without even caring about the evidence. I'm not sure which is scarier.
