Ratio of CD4:CD8 cells <1.4 14/28 (50.0)

*Lymphocyte subsets were defined as the following combinations: CD3+/CD45+ for CD3 T-lymphocytes; CD3+/CD4/+/CD45+ for CD4 T-lymphocytes; CD3+/CD8+/CD45+ for CD8 T-lymphocytes; CD19+/CD45+ for B-lymphocytes; and CD3+/CD(16+56)+/CD45+ for natural killer cells.
†CD45 lymphocyte count was designated the total lymphocyte count.
