Table 1 PSM Clusters population in group A and B before and after therapy vs. placebo

From: Psychometric evaluation of a radio electric auricular treatment for stress related disorders: a double-blinded, placebo-controlled controlled pilot study

PSM Clusters therapy (n = 150) ---- placebo (n = 50)
  Before After Before After
Loss of control and irritability n = 45 n = 16 p < .05 n = 14 n = 13 p > .05
Psycho Physiological sensation n = 50 n = 11 p < .05 n = 22 n = 20 p > .05
Effort sensation and confusion n = 65 n = 22 p < .05 n = 20 n = 20 p > .05
Anxiety and Depression n = 69 n = 15 p < .05 n = 20 n = 18 p > .05
Pain and Physical trouble n = 68 n = 27 p < .05 n = 30 n = 27 p > .05
Hyperactivity and acceleration n = 27 n = 14 p < .05 n = 12 n = 10 p > .05
  1. Group A show a significantly lower presence of symptomatic clusters after the treatment with p < .05, while Group B show very similar results before and after treatment p > .05
