Pooled results analyzed cure rates and Free T3/T4 changes. A subgroup analysis was conducted based on LiCO3 dosage and treatment duration, while meta-regression was performed to assess covariates such as the patient's age, RAI dose, and lithium dose.

Subgroup analysis revealed higher cure rates with short-duration intensified doses of LiCO3, while short-duration diluted doses reduced cure rates. No significant differences were noted in euthyroid and hypothyroid states. Changes in free T3 showed no significant difference between the arms at 7 days and the most common time point. A significant decrease in free T4 favored RAI with LiCO3 at 7 days (MD -4.90, 95% CI [-7.91, -1.89], p = 0.001), and the most common time point (MD -3.83, 95% CI [-7.45, -0.20], p = 0.04).
