DBP (mmHg)	74 (69, 78)	74 (70, 79)	0.718	0.000
MAP (mmHg)	92 (87, 96)	92 (87, 97)	0.955	0.000
R-R intervals (ms)	800 (724, 875)		768 (682, 853)	0.066 0.252
Up-cBRS	18.0 (13.1, 23.0)	16.0 (10.3, 21.7)	0.122	0.245

Data presented are means with 95% confidence intervals throughout the duration of the protocol (7 min). DBP, diastolic blood pressure; Down-cBRS, down-down cardiovagal baroreflex sensitivity; MAP, mean arterial pressure; mmHg, millimeters of mercury; ms, milliseconds; SBP, systolic blood pressure; Up-cBRS, up-up cardiovagal baroreflex sensitivity.
