Figure 3.

This is a bar graph showing the change in mean accuracy from the baseline for sentence production and sentence comprehension. The graph has two sections, A and B. Section A shows the change in mean accuracy from the baseline for sentence production. The x-axis shows the time points, 1 week post and 8 weeks post. The y-axis shows the change in mean accuracy from baseline. The graph shows that the change in mean accuracy from baseline for sentence production is significantly higher for the active group than for the sham group at the 1-week time point, with no significant differences at the 8-week time point. Section B shows the change in mean accuracy from the baseline for sentence comprehension. The x-axis shows the time points, 1 week post and 8 weeks post. The y-axis shows the change in mean accuracy from baseline. The graph shows that the change in mean accuracy from baseline for sentence comprehension is significantly higher for the active group than for the sham group at the 8-week time point, with no significant differences at the 1-week time point.

Sentence production and comprehension results. Change in accuracy between baseline and two follow-up time points (1 week and 8 weeks posttreatment) for transcranial direct current stimulation and sham stimulation. Results include changes to (A) sentence production and (B) sentence comprehension. A change above 0% indicates an improvement from the baseline, and a change below 0% indicates a decline from the baseline. Asterisks immediately above bars indicate a significant main effect at that time point. Vertical error bars indicate standard error.
