Percentage values represent the frequency (in percentage and absolute numbers) in median of T cells, CD4 T cells, CD8 T cells, and NK cells among all peripheral blood lymphocytes and the frequency of CD56 and CD56 NK cells among the NK cell population. Means and standard deviations (SD) are also shown. Significant values are highlighted in boldface type. a = statistical difference to the healthy group (); b = statistical difference to the HIV/AIDS group (). Statistical comparisons made by Kruskal-Wallis (with Student-Newman-Keuls posttest).
