Comparison of MSNA values at the operating point among each period

	Baseline	Post A	Post B	P (all)
MSNA BI, bursts/100 heartbeats	49.6 ± 6.0	69.2 ± 5.9*	69.5 ± 5.7*	<0.001
Total MSNA, units/beat	10.0 ± 1.1	17.0 ± 1.3*	17.6 ± 1.2*	<0.001
MSNA burst area, units/burst	20.0 ± 1.7	25.0 ± 2.7*	24.9 ± 1.9*	<0.001

Data are presented as means ± SE; n = 10 subjects. P (all): P value for the effect of time on the whole trial by linear mixed-effects model. *P < 0.05 compared with baseline by linear mixed-effects model (covariate; age and BMI). BI, burst incidence; BMI, body mass index; MSNA, muscle sympathetic nerve activity.
