Association between tidal volume 2-hr percent change and blood IL-6 change post exposure. Individual data are shown. Regression lines are shown by solid lines. Pearson partial correlations coefficients are reported, controlling for repeated measures of CAP<100 and CAP≥100. (A–C) CAP+O3 exposures: 10-min post; 3-hrs post; and 20-hrs post. (D–F) CAP exposures: 10-min post; 3-hrs post; and 20-hr post. There were significant positive associations between tidal volume percent change during CAP+O3 exposures and IL-6 changes at all three time points after but not for CAP alone exposures. Tidal volume 2-hr %Δ= 100 × [(2-hr minus 0-hr) / 0-hr]. Post ΔIL-6= post IL-6 minus pre-exposure IL-6. Abbreviations: CAP, concentrated ambient particle; O3, ozone.
