The possibility of an association of early pregnancy loss (EPL) with residential exposure to ELF magnetic fields was investigated in a case-control study. Eighty-nine cases and 102 controls were obtained from the data of an earlier study aimed at investigating the occurrence of EPL in a group of women attempting to get pregnant. Magnetic-field exposure was characterized by measurements in residences. Strong magnetic fields were measured more often in case than in control residences. In an analysis based on fields measured at the front door, a cutoff score of 0.5 A/m (0.63 microT) resulted in an odds ratio of 5.1 (95% confidence interval 1.0-25). The results should be interpreted cautiously due to the small number of highly exposed subjects and other limitations of the data.
在一项病例对照研究中，对早期妊娠丢失（EPL）与居住环境中极低频磁场暴露之间的关联可能性进行了调查。89例病例和102例对照来自一项早期研究的数据，该研究旨在调查一组试图怀孕的女性中EPL的发生情况。磁场暴露通过在住所进行测量来表征。病例住所中测量到强磁场的频率高于对照住所。在前门测量的磁场分析中，截止分数为0.5 A/m（0.63微特斯拉）时，比值比为5.1（95%置信区间1.0 - 25）。由于高暴露受试者数量较少以及数据的其他局限性，这些结果应谨慎解释。
