... has increased over decades. We evaluated whether the increased LT4 dosing influenced thyroid-stimulating hormone (TSH) and thyroxine (fT4) concentrations, growth, or treatment-related symptoms. Methods: LT4 doses, TSH, fT4, anthropometrics, and treatment-related symptoms until age 2 years were...

Results: Children with high-normal TSH (>3.0 mU/L) (28.8%) had higher BMI SDS compared to children with low-normal TSH (<3.0 mU/L) ( p < 0.001). Multivariable...
