BRS = baroreflex sensitivity [ms/mmHg], LF DAP = low frequency power of diastolic blood pressure [a.u.], LFu DAP = normalized low frequency power of diastolic blood pressure [%], TP DAP = total power of diastolic blood pressure [a.u.].
Comparison between Sepsis and Sham: *p-value < 0.05 (Wilcoxon rank sum test). Wilcoxon signed test: °p-value < 0.05 with respect to T1 (Friedman test p-value < 0.05).
