Table 3. Correlations of T cell percent antigen expression with cortisol measuresa.
| Cortisol Measures | Percent of CD8+ T cells with CD38+HLA-DR+ phenotype | Percent of CD4+ T cells with CD38+HLA-DR+ phenotype |
| Waking cortisol | 0.02 (−0.16, 0.19), p = 0.83 | −0.04 (−0.22, 0.13), p = 0.64 |
| 30 minute post-waking cortisol | 0.003 (−0.17, 0.18), p = 0.98 | −0.06 (−0.23, 0.12), p = 0.52 |
| Cortisol awakening responseb | −0.04 (−0.22, 0.14), p = 0.64 | −0.01 (−0.19, 0.17), p = 0.89 |
| Bedtime cortisol | 0.21 (0.04, 0.37), p = 0.02 | 0.15 (−0.02, 0.32), p = 0.09 |
| Cortisol slopeb | 0.16 (−0.02, 0.33), p = 0.09 | 0.16 (−0.02, 0.33), p = 0.09 |
a
The values presented are pairwise Pearson correlation coefficients between cortisol measures (log10 nmol/L) and lymphocyte phenotype, with 95 percent confidence intervals in parentheses, followed by P-values for the corresponding correlation coefficients. The N used to calculate the coefficients is 116–128.
