Analyzing the P1N1 amplitude range further substantiated the effects by demonstrating an almost significant difference for PVS (−1.6 μV ± 6.6 μV [SD]; p = 0.055, d = −0.24) and significant differences for tDCS (−1.9 μV ± 6.8 μV [SD]; p = 0.026; d = 0.28), as well as for both (1.9 μV ± 7.6 μV [SD]; p = 0.048, d = 0.24) compared no stimulation (3.1 μV ± 6.3 μV [SD]).
