Effects of active repetitive transcranial magnetic stimulation (rTMS), active transcranial direct-current stimulation (tDCS), and sham stimulation on average anxiety state (STAI-S). The scores were obtained before the first stimulation session (T0), after the 5th consecutive stimulation session (T1) and 30 days after (T2). For the sake of simplicity, and as the effects of sham rTMS and sham tDCS were remarkably similar regardless of the order in which they were conducted, we present the mean values grouped into a single sham-stimulation group. Error bars indicate standard error of the mean. STAI-S State-Trait Anxiety Inventory (state subscale).
