Transient Leukopenia After Radioactive Iodine Treatment in Patients With Graves' Disease: A Retrospective Cohort Study.

Context: Radioactive I (RAI) for the treatment of differentiated thyroid cancer is known to induce bone marrow suppression, which occurs approximately 1 month after treatment. However, it is unknown whether RAI therapy for Graves' disease causes bone marrow suppression.

Objective: This study aimed to evaluate the short- and long-term effects of RAI therapy on bone marrow function in patients with Graves' disease.
