summary - China Kadoorie Biobank: 512,891 adults aged 30-79 recruited 2004-2008 from 10 Chinese regions; 461,213 free of baseline cancer/CVD/diabetes analyzed, median follow-up 8.9 years (83,977 CVD cases, 9,985 CVD deaths). Daily egg consumption (usual ~0.76 egg/day) was associated with lower CVD risk than non/rare consumption (HR 0.89 for CVD; 0.88 IHD; 0.86 major coronary events; 0.74 hemorrhagic stroke; 0.90 ischemic stroke), with a significant dose-response trend, and 18% lower CVD death risk.
relevance_note - Largest single cohort in the slice (0.5M) and the clearest protective-direction hard-endpoint finding; central to the “not harmful, maybe protective at moderate intake” side.
