If the studies were done on the normal population, the vast majority of subjects will be eating very differently than a raw foodist, including consuming plenty of dietary cholesterol. For starters, cholesterol comes only from animal foods, so a vegan consumes no cholesterol at all. That alone could make the findings completely irrelevant for someone eating a raw diet, not to mention other factors like consumption of caffeine, alcohol, grains, refined sugar, preservatives, etc.
It would be like someone doing a study where 99.9% of the test group consisted of smokers. I wouldn't assume the results applied to me personally, since I'm not a smoker.
