Rice finding 2686
Source evidence and comparison details for the Rice profile.
Household rice (raw rice brought from home by a family member); form not stated · Methylmercury (MeHg) · 127 household rice samples (one per mother-child pair).
Selected finding and reference
127 household rice samples (one per mother-child pair). Basis: unspecified (basis not stated in main text; lab detail in Supplementary Materials, not in text copy).
All measurements exceeded the limits of detection (Lab analyses, p. 3); LOD value not given in main text
HMI baseline position
Limited data: The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference. Missing evidence never means low contamination.
The source reports a range, percentile or extreme value; only a mean, median or sample result can be positioned against a reference.
Reference version and interpretation
Frozen evidence selection: 2026-10-22. Method: hmi-pooled-reference-v2.
No admitted reference
The reference is computed by HMI from admitted evidence, not copied from a study baseline. It describes the evidence currently in this scope; it is not a worldwide or current-lot benchmark. Source, year and region filters do not change it. Different HMI scopes are not one common ranking.

All measurements exceeded the limits of detection (Lab analyses, p. 3); LOD value not given in main text
Shared samples and study overlap
Subgroup rows, statistics of the same subgroup and the study total share samples; they are not independent results.
Each table row describes a food/analyte result. Repeated rows do not add independent samples or datasets. No cross-study trend is calculated in this comparison mode.
