Abstract:
The association between residential radon exposure and the risk of childhood leukemia reported in this issue of Epidemiology may-or may not-justify further studies to confirm this finding. Such decisions could benefit from a more systematic approach than researchers ordinarily use. Furthermore, when considering the possibility of replication studies, epidemiologists need a new strategy-one that explores more explicitly the improvements and the additional study features that would be required to produce a more meaningful answer.
