ELF-003Retrieval lead
Personal magnetic measurements during pregnancy
The reported finding
Discovery dossier reports a miscarriage association with maximum, rather than average, measured magnetic field.
Reading it carefully
Original methods and exposure-day selection need checking before featuring.
Inside the study
Exposure conditions
24-hour personal monitoring during early pregnancy.
Design & controls
Prospective cohort; 969 participants reported in discovery dossier.
The protection question raised
Does a maximum magnetic-field reading capture a relevant pregnancy exposure or a measurement-day artefact? Original methods and exposure-day selection remain to be checked before this retrieval lead informs a health conclusion.
