↵2-150 Constant is the mean estimate at newborn age, QS state, and supine sleep position. The differences (Δ) were adjusted for other factors in the model and the baseline value centred at the mean.
↵2-151 Δ values represent the differences in the direction indicated for:
Age; newborn → 3 months
Sleep state; QS → AS
Position; supine → prone.
