Fig. 3From: Transcranial direct current stimulation (tDCS) for improving capacity in activities and arm function after stroke: a network meta-analysis of randomised controlled trialsNetwork graph of tDCS for improving arm function (measured by UE-FM) after stroke. The thicker the edge, the lower the standard error of this comparison. Colored polygons indicate multi-arm studies. UE-FM: Upper Extremity Fugl-Meyer AssessmentBack to article page
