(a) The interactions between TSH at 3–5years and TSH at 7–9years (p of 3–5 years = 0.99, 7–9 years = 0.38, Interaction = 0.84.); (b) The interactions between Free T4 at 3–5years and Free T4 at 7–9years (p of 3–5 years = 0.52, 7–9 years = 0.45, Interaction = 0.28.); (c) The interactions between Free T3 at 3–5years and Free T3 at 7–9years (p of 3–5 years = 0.12, 7–9 years = 0.02, Interaction = 0.97).
