a statistical trendp = .076
However, because of high variability over participants, the p -values from two-tailed paired-sample Student's t -tests did not reach statistical significance (all p > .05), there being merely a statistical trend ( t (13) = –1.93, p = .076) observable for alpha-gamma coupling during visual TMS, suggesting stronger ERPAC enhancement by rTMS than by sTMS. 3.2.
