Means ± standard error of the mean of the Change-Intensity Index of the outcome parameters (delta visual analog scale scores) of anxiety, tension, anger/aggression, and mood within each treatment group at single weeks. The more the Change-Intensity Index diverges from 100% towards 200% or 0%, the stronger it demonstrates the treatment’s effects compared to baseline (no treatment). The p values indicate the significance of the deviation of the Change-Intensity Index from 100 (no-treatment effect) by one sample t-tests. No-treatment scores are theoretically mathematically assumed reference scores. AA = auricular acupuncture; PMR = progressive muscle relaxation; SEM = standard error of the mean.
