27 premenopausal women + 25 men, same 640 mg/d egg-cholesterol crossover design as the sex-specific Herron papers. LDL particle-size distribution shifted toward the larger, less-atherogenic LDL-1 subclass during the high-cholesterol period in both hypo- and hyperresponders (shift larger in hyperresponders); women had a larger baseline LDL peak particle diameter than men.
relevance_note: Shows response-classification changes the magnitude but not the direction of a favorable LDL particle-size shift — a pro-egg qualifier that applies even to hyperresponders, independent of the classification itself.
