tendency towards significancep = 0.068
Post-hoc tests showed a tendency towards significance: for lower beta at baseline (i.e., − 14.6 power units), HD-tDCS reduced RTs compared to sham (1514 ms vs. 1634 ms, p = 0.068).

Furthermore, data showed a trend towards a behavioural effect of HD-tDCS in participants with lower beta at baseline showing faster response times.
With respect to behavioural outcomes, HD-tDCS produced some preliminary evidence (i.e., a trend towards significance) of a potential motor improvement in participants who had lower beta power at the baseline stage.
