Figure 4

Scatterplot of changes in State-Trait Anxiety Inventory-State Anxiety (STAI-SA) scores (a) in the active stimulation group and (b) sham stimulation group, and in State Trait Anxiety Inventory-Trait Anxiety (STAI-TA) scores c in the active stimulation group and (d) sham stimulation group. (a) No significant correlation was found (ρ = 0.26, S = 2166, p = 0.20). (b) No significant correlation was found (ρ = –0.10, S = 4010, p = 0.62). (c) Spearman’s rank correlation coefficient showed a significant correlation between changes in STAI-TA scores and changes in current density in the active stimulation group (ρ = 0.63, S = 1083, p < 0.01). (d) No significant correlation was found (ρ = 0.024, S = 3567, p = 0.90).
