Figure 4.
Change in percentage of complete utterances. A change between baseline and two follow-up time points (1 week and 8 weeks posttreatment) for transcranial direct current stimulation (tDCS) and sham stimulation. A change above 0% indicates improvement from the baseline, and a change below 0% indicates a decline from the baseline. Brackets indicate a significant difference between tDCS and sham at that time point. Vertical error bars indicate standard error.
