Figure 2. Top age-associated immunological parameters in HIV-negative and HIV-positive study participants. (A) Venn diagram showing the number of parameters with significant correlations with chronological age in HIV-negative (n = 103) and HIV-positive (n = 106) groups. Bar graph showing directionality of correlation coefficient for the top parameters with significant correlations with age in HIV-negative (B) and HIV-positive (C) participants. In red font are non-T cell parameters. Bold font indicates CD38 and HLADR containing parameters. Spearman test was performed for each parameter and chronological age, p < 0.05 was considered significant. In bar graphs, red denotes a positive correlation and blue denotes a negative correlation.
