Results of the clinical laboratory differences for CD3%, CD4%, WBCs, IgA, and zinc/copper ratio. When applying a cutoff at age 5, separating the younger four children from the older six children, significant decreases were seen for CD3% (p = 0.036) and CD4% (p = 0.028), and a significant increase was seen for WBC (p = 0.031). Trends for increased IgA (p = 0.059) in the younger cohort and elevated zinc/copper ratios (p = 0.061) in the older cohort were present. For CD3% change, two points overlap at +2 in the older cohort. For CD4% change, two points overlap at both – 1 and +1 in the older cohort. In the older cohort for IgA change, two points overlap at – 15.
