  1. HP = heart period; µHP = HP mean; σ2 HP = HP variance; SAP = systolic arterial pressure; µSAP = SAP mean; σ2SAP = SAP variance; LF = low frequency; HF = high frequency; HFHP = power of the HP series in the HF band; LFSAP = power of the SAP series in the LF band; BRS = baroreflex sensitivity; α = BRS via the spectral method; αLF = α in the LF band; αHF = BRS in the HF band; K2 = squared coherence; Ph = phase relationship; BRSLF = BRS via the cross-spectral method in the LF band; K2LF = K2 in the LF band; PhLF = Ph in the LF band; BRSHF = BRS via the cross-spectral method in the HF band; K2HF = K2 in the HF band; PhHF = Ph in the HF band. Data are presented as mean ± standard deviation. The symbol * means p < 0.05 versus CEA within the same time point, while the symbols § and # indicate p < 0.05 versus PRE and FU6 respectively within the same group.
