Controls 300) selected by random digit dialing Medicare eligibility lists. Exposure status, defined as ever having been employed job which has classified involving potential fields, was assigned without knowledge case/control status. An elevated found for any with (odds ratio (OR) 1.8, 95 percent confidence interval (CI) 1.0-3.7), highest among electricians, telephone linemen, electric power workers (OR 6.0, CI 1.7-21) radio communications 2.9, 0.8-10). Risk did not vary duration exposed employment. The subjects who first jobs before age 30 years initially at least prior diagnosis.
