O-64 - Phosphatidylcholine capsules at a matched choline dose did not raise TMAO or platelet reactivity
The phosphatidylcholine capsule arm delivers choline in the same phospholipid form as egg yolk but without the egg food matrix, and reproduces the egg null - isolating choline form as the relevant variable rather than the whole-egg matrix per se.

Why this is evidence
Choline delivered in egg’s phospholipid form (phosphatidylcholine) at a matched dose does not raise TMAO or platelet reactivity — the egg-choline candidate of H-54 is not operative — leaving cholesterol (H-26) as the egg-intrinsic candidate.
