Relation of logarithmic zinc concentration with age in autistic children.
The association of hair logarithmic zinc concentration with age in autistic children (N = 1,967) is shown. Each point represents the corresponding age and logarithmic zinc concentration of the individual child. Two dotted horizontal lines represent the ±2 S.D. levels of the reference range (86.3–193 ppm) of hair zinc concentrations. A significant relation of the zinc concentration with age (r = 0.367, p < 0.0001) in the autistic children is shown.
