This study is dedicated to addressing the lack of research on the most effective dosage of long-acting growth hormone for children with short stature. By employing clinical trial design, we are committed to investigating the therapeutic benefits and safety profiles associated with varying doses of long-acting growth hormone. Our ultimate goal is to offer clinicians more precise treatment guidance and assist patients in attaining optimal growth and developmental outcomes.
