Figure 1From: Greater frequency of CD5-negative CD8+ T cells against human immunodeficiency virus type 1 than other viruses is consistent with adaptation to antigenic variationComparison of the percentage of circulating CD8+T cells expressing CD5 in HIV-infected individuals and healthy controls. The median percentage of circulating CD8+ T cells expressing CD5 measured by flow cytometry is shown for each group by a horizontal line bisecting the data points with upper and lower horizontal lines in each group indicating interquartile range. Significant difference between the medians is indicated by the p value above the line spanning the data sets (Mann–Whitney test).Back to article page
