Fig. 3. Increased BP variability in conscious nodose/petrosal ganglia-specific dKO mice.

A, Continuous measurements of mean arterial pressure (MAP) and HR over 72 h, binned by hour. The differences between groups were significant during night (gray shading, two-way ANOVA, means ± s.e.m). B, Average MAP and HR during day (6am-6pm) and night (6pm-6am). C, sBRS, expressed as change in PI (ms) per change in systolic BP (mmHg), was significantly reduced in dKO mice (n = 17) compared to WT (n = 15). D, Frequency distribution histogram of the systolic blood pressure from 72 h. Red arrows indicate wider distribution of BP in dKO mice. E, BP variability reported as standard deviation from 72-h period. F, Maximum and minimum BP values. P values are indicated in the bars. *p < 0.05, **p < 0.01 and ***p < 0.001, n.s. is not significant. Unpaired Student’s t-test unless indicated otherwise, means ± s.e.m. n = 7–17.
