Figure 9.
Effects of tcVNS (red lines, right side) or sham (blue lines, left side) on interleukin-6 (IL-6) at baseline (base) and following three months of double blind active tcVNS or sham treatment in patients with PTSD. Lines connect baseline to post-treatment and post traumatic script stress in 5/9 patients and bars represent the means for each group. There was a significant increase in IL-6 in the sham group (*p<0.05) not seen in the PTSD group.
