Figure 4.

A bar graph showing the mean percentage of complete utterances, change from baseline for active and sham stimulation for 2 time points. The data for active stimulation are as follows. 1 week post: 9 percent. 8 weeks post: 5 percent. The data for sham stimulation are as follows. 1 week post: 15 percent. 8 weeks post: negative 4 percent. An asterisk is marked over each bar corresponding to 1 week post.

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.
