Table 3 Changes in the VAS loudness and VAS uncomfortable scores

From: A comparative study on the effects of systemic manual acupuncture, periauricular electroacupuncture, and digital electroacupuncture to treat tinnitus: A randomized, paralleled, open-labeled exploratory trial

  1. MA systemic manual acupuncture group, PE periauricular electroacupuncture group, DE distal electroacupuncture group, VAS visual analogue scale. All variables are expressed as mean ± standard deviation analyzed by one-way analysis of covariance considering THI score at baseline as covariate. A p-value < 0.05 was considered significant. Different letter superscripts in the same column indicate a significant difference (*p < 0.05, LSD post-hoc test)
