Does radioiodine therapy for hyperthyroidism increase long-term morbidity?

摘要

This was a population-based, case-control study of patients with hyperthyroidism who were treated with radioiodine therapy at a single center in Finland between January 1969 and June 2002. The patient group comprised all incident cases of radioiodine-treated hyperthyroidism in the base population. The control group comprised age-matched and sex-matched healthy individuals identified from a population registry. Control individuals had to be alive at the time the matched patient first received radioiodine treatment; however, there were no other inclusion or exclusion criteria.
