Values from N = 17 subjects.
HR, heart rate (beats/min); PWVcf, pulse wave velocity at the carotid and femoral artery.
Matched-pairs t test was used to examine preintervention vs postintervention survey measures and clinical measure differences.
*
Denotes significance with an α set at .05.
a
Nonparametric Wilcoxon signed rank test was used for these values.
b
Ten individuals were found to have valid arterial function measurements (per expert blinded review) to be used in the analysis.
c
Not significant after Benjamini-Hochberg test was completed using a false discovery rate of 10%.
d
Data presented as means ±SD.
