Figure 4. Effects of taVNS on IBS-QOL scores and IBS-SSS.

Figure 4

(A and B) taVAS increased IBS-QOL score (A) and decreased IBS-SSS (B). The independent sample t test was used to assess the difference between the sham-taVNS and taVNS groups. The paired Student’s t test was applied to evaluate the differences before and after the taVNS or sham-taVNS treatment. Mean ± SD is presented (versus sham-taVNS, *P < 0.05, ***P < 0.001; versus baseline, ###P < 0.001). At baseline, both groups, n = 21. After treatment, taVNS group, n = 21; sham-taVNS group, n = 19.
