rTMS versus ctDCS versus sham – change in primary outcomes relative to baseline at post-treatment (day 1) and at one-month follow-up (day 30).

Medians (and interquartile ranges) are displayed for each intervention condition as well as p-values of median tests. Significance level =.05. Post-hoc tests p-values are adjusted with the Bonferroni correction.
BNT: Boston naming test; SF: semantic fluency, TT: token test.
