About 4 in 10 patients with Graves' disease who need a permanent treatment cannot receive radioactive iodine because they are pregnant, breastfeeding, have thyroid cancer, severe eye problems, or refuse radiation—so surgery is their only option.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
The pooled prevalence of absolute and relative contraindications to radioactive iodine therapy across diverse populations and healthcare systems in patients with Graves' disease requiring definitive treatment.
A systematic review and meta-analysis of all prospective cohort studies and registry data reporting the proportion of Graves' disease patients referred for definitive therapy who have contraindications to RAI (pregnancy, breastfeeding, thyroid cancer, ophthalmopathy, age <18, patient refusal), stratified by region, age, and guideline adherence.
The incidence and persistence of contraindications to radioactive iodine over time in a defined population of Graves' disease patients referred for definitive therapy.
A prospective cohort study following 1,500 adults with Graves' disease referred for definitive treatment, documenting at baseline and 6-month intervals whether pregnancy, breastfeeding, ophthalmopathy, thyroid cancer, or patient refusal renders RAI contraindicated, with outcomes tracked for 5 years.
The current prevalence of contraindications to radioactive iodine therapy among patients presenting for definitive treatment of Graves' disease in a single healthcare setting.
A cross-sectional survey of 2,000 consecutive patients with Graves' disease referred for definitive therapy across 10 tertiary centers, recording documented contraindications to RAI (pregnancy, breastfeeding, thyroid cancer, ophthalmopathy, age, refusal) at the time of initial consultation.
Rare or atypical contraindications to radioactive iodine therapy not captured in larger studies, such as unusual patient refusal patterns or unexpected drug interactions.
A case series of 50 patients with Graves' disease who were deemed ineligible for RAI due to unusual or previously unreported contraindications, including detailed documentation of clinical reasoning, patient counseling, and alternative treatment outcomes.
Consensus among endocrinologists and surgeons on which conditions should be considered absolute or relative contraindications to radioactive iodine therapy in Graves' disease.
A Delphi consensus study involving 50 international thyroid experts rating the strength of evidence for each potential RAI contraindication (pregnancy, breastfeeding, thyroid cancer, ophthalmopathy, age, refusal) on a 9-point scale, with iterative feedback until 80% agreement is reached.
