Overview of the correlations illustrating the relationships between the changes in attention bias, STAI trait anxiety score, and attention bias in the sham condition. (A) Correlation matrix of three indices, with the look-up table indicating the correlation coefficients. (B) Venn diagrams showing the relationships between three indices. The thick arrows indicate partial correlations between the baseline bias score and changes in attention bias in both tRNS and tDCS with the STAI trait anxiety score as a control variable. (C) Scatter plots depicting changes in attention bias for tRNS and tDCS against attention bias in the sham condition. The straight and curved lines represent the estimated regression lines and 95% confidence intervals, respectively. * indicates a permuted p-value.
