However, systematic meta-analyses found no effect, but all of these analyses pooled data from both single and repetitive sessions at the group level. The aim of this paper was to perform a meta-analysis based on individual patient data to explore the effects of repetitive tDCS sessions on naming in post-stroke aphasia and in prespecified subgroups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      We searched for published sham-controlled trials using the keywords \u201caphasia OR language\u201d AND \u201ctranscranial direct current stimulation OR tDCS\u201d AND \u201cstroke\u201d. We computed an active and sham improvement ratio by dividing the difference between naming scores after and before the active or sham sessions, respectively, by the total number of picture items. Because of heterogeneity (I\n                      <jats:sup>2<\/jats:sup>\n                      \u200a=\u200a66%, p: 0.002), we used random-effects models to estimate the standardized mean difference (SMD) for the naming outcome. We then analyzed subgroups according to number of sessions, polarity, side\/location of the active electrode, post-stroke delay, aphasia severity and comprehension disorders.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Seven eligible studies were identified, including 68 chronic stroke patients. tDCS was beneficial on naming ability (35% \u00b134% in the active vs. 25% \u00b137% in the sham condition). An SMD of 0.8 (95% CI: 0.27\u20131.33) was found for the naming outcome. Additionally, there was a dose-dependent effect (5 vs. &gt;5 sessions). We also demonstrated a prevalence of anodal vs. cathodal condition and left vs. right targeting electrode. Finally, repetitive sessions were beneficial regardless of the severity of aphasia, comprehension disorders or post-stroke delay.<\/jats:p>\n                  <\/jats:sec>\n
