Aim of study (acc. to author)
Further details
Following electromagnetic field-related aspects were studied: working under magnetic field for more than 10 years and electrical injury. Furthermore, family history of disease, smoking, occupation, living place (rural/urban), source of drinking water, exposure to insecticides, pesticides, heavy metals (iron), solvents, and chemicals were investigated.
