Association between basal HRV indices (calculated at t = 0, just prior to LPS administration) and area under curve of the LPS-induced proinflammatory cytokine response (TNFα and IL-6, log pg/ml/hour) of 40 subjects. ms, milliseconds; AU, arbitrary units. Solid and dashed lines, TNFα and IL-6 regression lines, respectively. Pearson correlation coefficients (none statistically significant) indicated.
