# ELF-004 — Later miscarriage cohort with editorial notice

Why this matters
The reported miscarriage association concerns power-frequency magnetic fields, not wireless RF. An editorial Expression of Concern states that participant consent did not allow data sharing, limiting independent reanalysis. This is not a retraction, but the restriction affects how much weight the finding can carry.

Topic: Power frequency fields

Verification Group: Editorial notice flagged

Record Role: Notice flagged retrieval lead

Featured: False

Exposure: 24-h EMDEX Lite power-frequency magnetic-field monitoring; 99th-percentile exposure classification. The meter does not establish RF wireless exposure.

Design: 913 pregnancies reported in discovery dossier.

Finding: Prospective miscarriage association reported in 913 pregnancies; retained with the linked Expression of Concern, without a featured numerical risk claim.

Boundary: Underlying data cannot be shared because retrospective participant consent is unavailable, per notice. This is an Expression of Concern, not a retraction. No RF causal inference; not used centrally.

Protection Question: How much weight can the miscarriage association carry without independent reanalysis of the data? The consent-related Expression of Concern remains material, and this power-frequency observation is not an RF causal finding.

Access: Original indexed methods and official 2021 notice reviewed

Notice: Editorial Expression of Concern, 10 March 2021, DOI 10.1038/s41598-021-85479-w. Notice says data unavailable for readers wishing to repeat analyses because consent for sharing was not obtained.

Funding: Not established from retrieved material.
