Aim of study (acc. to author)

A case-control study was conducted in Rhode Island to investigate the relationship between childhood leukemia and electric power lines.

Further details

Exposure was assessed by calculation based on type of power lines and distance of residence to power lines below 45.7 m for each address. The quartile values of exposure for the control addresses was used to categorize the exposure of the case addresses into 4 groups: very low, low, high and very high.
