ELF-004Editorial notice flagged
Later miscarriage cohort with editorial notice
The reported finding
Prospective miscarriage association reported in 913 pregnancies; retained with the linked Expression of Concern, without a featured numerical risk claim.
Reading it carefully
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.
Inside the study
Exposure conditions
24-h EMDEX Lite power-frequency magnetic-field monitoring; 99th-percentile exposure classification. The meter does not establish RF wireless exposure.
Design & controls
913 pregnancies reported in discovery dossier.
The protection question raised
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.
