Effects of transcranial direct current stimulation on language function in adult with poststroke aphasia: A network meta-analysis and systematic review of randomized controlled trials

The assessment included seven items: random sequence generation, allocation concealment, blinding of participants and investigators, blinding of outcome assessors, completeness of outcome measures, selective reporting, and other bias. Each item was graded as high risk, low risk, or unclear. All study data were well-integrity and no selective reporting occurred; no other bias was reported in any RCT. All included studies used efficacy rate to evaluate efficacy. A meta-analysis was performed on 10 studies, and the heterogeneity test I0 = 0, it was considered that the studies were homogeneous. The effective rate of the treatment group was significantly better than that of the control group, and the difference was statistically significant.
