An obvious factor to look at among the subjects would be body fat level.

Maybe many of those who consumed more eggs or cholesterol simply just ate more.

If the study simply tracked calories, maybe calories would be found to be correlated with CVD risk.

Problem with that, you can't really track what some people eat for 30 years.

100% this. They don't control for lean mass or anything like that, so it's hard to say if it's the cholesterol or simply overeating that is the problem. I want to see a study where Calories and Macros are held the same but one group eats more cholesterol than the other and see what those results look like. Sadly those kinds of studies are very hard to do in the nutritional space.
