O-42 - Only 8 percent of participants ate at least one egg serving per day in the pooled US cohorts
Only 0.2% consumed >=1 serving/day of all four less-healthy foods (eggs, processed meat, unprocessed red meat, poultry) simultaneously. The steepest substitution benefits (down to HR 0.46) are for these small high-intake subsets with “greater room for reducing intake.”

Why this is evidence
In the pooled US cohorts only 8% eat >=1 egg/day, so the Western estimates carry little information at higher intakes. This supports H-50’s exposure-range / statistical-power origin of the region contrast (the West cannot resolve high-intake effects); H-22 and H-7 do not predict it.
Likelihood
# E-130 (HC-2) — lone edge, one observation O-42 "in pooled US cohorts 58.5% eat >=1 egg/week but only 8.0%
# eat >=1 egg/day — the West carries little information at higher intakes." Members in HC-2.hypotheses order
# [H-7, H-22, H-50]. Anchored on H-50 = 1 (best fit); others as ratios (rule 7).
lik_o42_H50 = 1.0 # anchor: the West's sparse high-intake data is exactly H-50's exposure-range / statistical-
# power origin of the region contrast — the Western "null" is partly non-informativeness
# (cannot resolve high-intake effects), not a genuine regional difference; A-14 (approved)
# confirms the per-day estimates rest on the 8% high-intake minority
lik_o42_H22 = 0.6 # 0.6×: genuine region-modification does not predict/need the Western null to stem from
# sparse high-intake sampling; this observation supplies a power-artefact alternative to
# H-22's "genuinely null in the West," mildly against
lik_o42_H7 = 0.7 # 0.7×: H-7 concerns the ASIAN inverse being confounding and is largely silent on Western
# exposure ranges — roughly neutral; slightly above H-22 because H-7 stakes no claim on
# the West being a genuine null that this power-artefact could undercut
t_o42 = 0.62 # cap = trust_score of O-42's source S-89 = 0.62. O-42 is a simple descriptive intake-
# distribution tabulation (% consuming), reliable at the source level; no dock, at cap
