The Study
Remission, Relapse, and Thyroid-Related Parameters Measurement at Discontinuation of Low-Dose Anti-Thyroid Drugs in Graves' Disease.
This study looked at people who had Graves' disease and stopped their medicine to see who got sick again. It found that younger people and those with higher antibody levels were more likely to get sick again, but it didn't prove that the antibodies made them sick—it just noticed they often happened together.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
Doctors gave medicine to people with Graves' disease until their thyroid got better, then stopped the medicine to see who got sick again.

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Even with high TRAb, many people didn't relapse — so TRAb alone can't reliably tell if someone will get sick again.
- 2Of 1,508 people, 435 got sick again (29%).
- 3Those who were younger, had higher antibody levels (TRAb), and lower TSH when stopping medicine were more likely to relapse.

Patients with Graves' disease who stop anti-thyroid drugs before 18 months of treatment are more likely to experience a return of the disease than those who complete at least 18 months of therapy.
Patients with Graves' disease who stop anti-thyroid drugs before 18 months of treatment are more likely to experience a return of the disease. Sustained remission is uncommon without at least 18 months of continuous therapy.
Anti-thyroid medications lower the amount of thyroid hormones produced by the thyroid gland.
