Fig. 3From: Cumulative physiological stress is associated with age-related changes to peripheral T lymphocyte subsets in healthy humansAssociation between physiological stress load and naïve and memory Tregs. Frequency of (A) naïve Tregs and (C) memory Tregs grouped by subject age. Statistical analysis was performed using Kruskal-Wallis non-parametric one-way ANOVA; ***P < 0.001. Not age-adjusted and age-adjusted linear regression of (B) naïve Treg frequencies and (D) memory Treg frequencies and physiological stress load. Equation, correlation squared (R2), P value for the association constant, and number of subjects are shown for each linear regressionBack to article page
