Relationship between hemoglobin and insulin-like growth factor-1 in children and adolescents with idiopathic short stature.

This study demonstrated that Hb is associated with IGF-1 in Chinese children and adolescents with ISS. The levels of IGF-1 increased with the elevation of Hb, but when the concentration of Hb exceeded a certain range, with the increase of Hb, IGF-1 decreased instead.
