Input: Consider Input: Question: Do small changes in thyroxine dosage produce measurable changes in hypothyroid symptoms , well-being , or quality of life : results of a double-blind , randomized clinical trial?
Answer: Small changes in T(4) dosage do not produce measurable changes in hypothyroid symptoms, well-being, or quality of life, despite the expected changes in serum TSH and markers of thyroid hormone action. These data do not support the suggestion that the target TSH range for the treatment of primary hypothyroidism should differ from the general laboratory range.
Output: no
