Relationships between mean cytokine/chemokine rankings and age of rhesus macaques. Animals were ranked from 1 (low) to 101 (high) for each positively correlating cytokine/chemokine (and in reverse for each inversely correlating factor). Mean rank values of the group of factors exhibiting concordant pairwise correlation coefficients (Panel A) and the remaining cytokines/chemokines (Panel B) were plotted against the age of each monkey. Pearson correlation coefficients were calculated between the mean rank values and age, and P < 0.05 was considered statistically significant.
