  1. GOS is the Glasgow outcome scale, GCS is the Glasgow coma scale, CV is the cerebral vasospasm, DCI is the delayed cerebral ischemia, ∆TCBFV is the time difference between cerebral blood flow velocity and arterial blood pressure, Mx is the mean flow autoregulation index, BRSdrop and BRSrecovery are the baroreflex sensitivity indices calculated as ratios between changes in interbeat interval and changes in arterial blood pressure (∆TIBI/∆ABP) during the boot deflation cycle at falling and recovery moments, IQR is the interquartile range, std is the standard deviation, Surv. is the survivor group, and Cont. is the control group. The asterisk (*) indicates statistical significance (p < 0.05)
