Fig. 1. The taxonomic composition of the gut microbiota in conscious patients (n = 19) and vegetative state patients (n = 10) compared to the reference ranges (shown in blue) provided by the manufacturer. Twenty parameters were compared

Fig. 3. Blood serums concentrations of IL6 and cortisol in patients with different GCS scores (p < 0.05 for comparison between groups scoring 15 and 14–13 points and between groups scoring 15 and 12–6 points)
