| cBRSnPRSA [ms⋅mmHg-1] | 4.20 ± 3.45 | 4.336 ± 3.33 |
| sBRSSEQ [bursts⋅s-1⋅mmHg-1] | -0.072 ± 0.026 | -0.099 ± 0.062# |
| sBRSPRSA [bursts⋅s-1] | -0.017 ± 0.012 | -0.016 ± 0.012 |

AP, arterial pressure; BR, baroreflex; cBR, cardiac BR; sBR, sympathetic BR; cBRS, cBR sensitivity; sBRS, sBR sensitivity; ΔAP+, positive AP variation; ΔAP-, negative AP variation; SEQ, sequence method; PRSA, phase rectified signal averaging method; nPRSA, normalized PRSA. Data are presented as mean ± standard deviation. The symbol # indicates p < 0.05 versus ΔAP+. ΔAP is intended as ΔSAP for the computation of cBRS and ΔDAP for the computation of sBRS.
