Relation of logarithmic magnesium concentration with age in autistic children.
The association of hair logarithmic magnesium concentration with age in autistic children (N = 1,967) is shown. Each point represents the corresponding age and logarithmic magnesium concentration of the individual child. The dotted horizontal lines represent the ±2 S.D. levels of the reference range (9.6–163 ppm) of hair magnesium concentrations. A significant relation of the magnesium concentration with age (r = 0.362, p < 0.0001) in the autistic children is shown.
