Egg consumption shows cardiovascular disease risk associations at high intake but not at moderate intake around one egg per day.

Triggered by the diabetes subclaim ('Positive egg–CVD associations are concentrated among people with diabetes') moving from supported (0.8) to contested (0.5). That subclaim sits in the 'against' (subgroup/population, not dose) argument. Judged the change non-material to the parent's status: weakening a rival explanation supplies no positive evidence for the dose-threshold reading, and the parent's contested status rests on the unestablished high-intake-harm half (b), which is untouched. Kept status contested at confidence 0.78. Refreshed the reasoning trace, which had stale subclaim statuses (diabetes subclaim described as 'assessed supported', population subclaim as 'unassessed'); both are now recorded as contested (0.5 and 0.7). Reaffirmed importance at 0.4 with contestation 0.75. No structural changes; decomposition remains apt. No dependent notification: parent status unchanged and no material shift a dependent steward would need to re-triage (the diabetes subclaim change was itself the trigger, propagated from below).

Structured and assessed
First pass. Decomposed the conjunctive dose-threshold claim into a 'for' argument (created novel subclaim 'High egg consumption is associated with increased CVD risk in a dose-response manner', importance 0.4, supports) and an 'against' argument grouping two existing claims linked as contradicts: population heterogeneity (a4173db8) and diabetes-subgroup concentration (31d170ee), which offer competing explanations to a dose threshold. The moderate-intake half matched the parent claim fadbc1c1 (Matcher, 0.78), so I did not duplicate it as a subclaim to avoid a circular edge; it is handled in prose. Wrote both argument forms. Kept importance at 0.4 (notable, contested, but narrower than the headline egg–CVD debate). Assessed CONTESTED (confidence 0.78): the moderate-safety half is well supported (BMJ 2020 / ~1.7M meta; AJM meta), but the high-intake-harm half is disputed (Zhong 2019 dose-response vs several null/inverse analyses and confounding), and rival population/subgroup accounts are live. No single credence given (composite pulls both ways). Canonical form left as-is; it is neutral, ~18 words, and states the proposition as debated.

This claim combines a well-supported half with a disputed one. That moderate egg consumption, around one egg per day, carries no clear increase in cardiovascular disease risk is backed by large pooled evidence: an updated meta-analysis of roughly 1.7 million participants and three large US cohorts found no association between intake of up to one egg daily and cardiovascular disease. The other half, that risk associations emerge at high intake, is where the evidence diverges. One influential pooled analysis of US adults reported a dose-response pattern in which each additional half-egg per day was associated with modestly higher cardiovascular disease and mortality, but several other meta-analyses find no increased cardiovascular disease even above one egg per day, and cohorts in Europe and Asia often report null or even inverse associations at comparable intakes. The upshot is that a clean moderate-safe, high-harmful threshold is one plausible reading of a heterogeneous literature rather than an established finding. Competing accounts fit the same data: the positive associations appear concentrated in US populations and among people with diabetes, suggesting that who is eating the eggs, and residual confounding from correlated dietary and lifestyle factors, may explain the signal better than intake dose alone. The question would be resolved by consistent, confounder-adjusted dose-response data across populations at genuinely high intakes; at present the high-intake half remains genuinely disputed.
