Figure 6.
The effect of OVA sensitization on HRV during the light and dark cycles immediately following aerosol challenge. During the light cycle, OVA sensitization resulted in decreased LF relative to Alum controls (3–10 h; P < 0.05). During the dark cycle, OVA sensitization resulted in decreased RMSSD (P < 0.025), pNN6 (P ≤ 0.001), LF (P ≤ 0.001), HF (P < 0.05), and LF/HF (P ≤ 0.001; Two-Way ANOVA with Holm-Sidak post-hoc analyses; *P < 0.05).
