The values shown represent the percentage and absolute number in median within each cell population expressing a given receptor NCR. Means and standard deviations (SD) are also shown. Significant values are highlighted in bold. a = statistical difference to the healthy group (); b = statistical difference to the HIV/AIDS group (). Statistical comparisons were made by Kruskal-Wallis (with Student-Newman-Keuls posttest).
