That's a 25-year-old revisit of even older studies dating back as far as 1960... none of which controlled for key elements like carbohydrate intake.
Even so, check out this element of its conclusions:
"The greatest response is expected when baseline dietary cholesterol is near zero, while little, if any, measurable change would be expected once baseline dietary cholesterol was > 400-500 mg/d. People desiring maximal reduction of serum cholesterol by dietary means may have to reduce their dietary cholesterol to minimal levels (< 100-150
mg/d) to observe (even) modest serum cholesterol reductions while persons eating a diet relatively rich in cholesterol would be expected to experience little change in serum cholesterol after adding even large amounts of cholesterol to their diet."
It didn't even differentiate HDL from LDL, let alone the actually harmful subsets like small-particle LDL.
