CD3+/CD4+ and CD3+/CD8+ absolute counts over 7-year period. The patient’s absolute T-cell counts of CD3+/CD4+ and CD3+/CD8+ measured in cells/mm3 are shown based on the amount of time in months post-thymectomy. The red data points represent CD3+/CD8+ absolute cell counts; the blue data points represent CD3+/CD4+ absolute cell counts. Age-appropriate T-cell counts are represented by the vertical brackets, with values provided in the adjacent boxes. The red bracket corresponds to normal CD3+/CD8+ absolute cell counts, and the blue bracket corresponds to normal CD3+/CD4+ absolute cell counts.
