Published in: J Epidemiol 2010; 20 (1): 54-61
Aim of study (acc. to author)
Endpoint/type of risk estimation
Type of risk estimation:
(odds ratio (OR))
questionnaire: mother's and child's use of electric appliances measurement: 1-week-long continuous measurement at 30-sec intervals in the
child's bedroom and 5-min-long spot measurement at several points inside and outside the house calculation: distance from residence to nearest
high voltage power line based on maps provided by the power companies and geographical information system sofware Exposure groups
