Cardiovascular and respiratory parameters during the carbon dioxide reactivity test

Healthy + CVD Risk	Sham		RIPC		Sham v RIPC P value
	Baseline	5% CO2	Baseline	5% CO2
MCAv (cm/s)	64 ± 12	83 ± 19*	63 ± 11	83 ± 18*
PetCO2 (mmHg)	34 ± 6	44 ± 3*	34 ± 6	44 ± 3*
MAP (mmHg)	101 ± 8	108 ± 9*	100 ± 5	106 ± 6*
MCA reactivity to CO2 (cm/s/mmHg)	1.97 ± 0.88		2.06 ± 0.69		0.61

Values are means ± SD. Data are presented grouped (Healthy and CVD risk) as there were no significant interactions between participant groups. Statistical significance was set at P < 0.05
