This calculator is based on the GREAT and GRES recurrence risk assessment scales published domestically and internationally. It aims to assist clinicians in evaluating the recurrence risk of new patients after antithyroid drug (ATD) treatment, providing a reference for formulating precise treatment plans.

It should be noted that to fully utilize the predictive value of this calculator, patients should have good treatment compliance, reasonable medication use, and a healthy lifestyle (e.g., quitting smoking).
