What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTranscranial direct current stimulation (tDCS) is a brain stimulation technique used to examine causal relationships between brain regions and cognitive functions. The effects from tDCS are complex, and the extent to which stimulation reliably affects different cognitive domains is not fully understood and continues to be debated. OBJECTIVE/HYPOTHESIS: To conduct a meta-analysis of studies examining the effects of single-session anodal tDCS on language.
methodsThe meta-analysis examined the behavioral results from eleven experiments of single-session anodal tDCS and language processing in healthy adults. The means and standard deviations of the outcome measures were extracted from each experiment and entered into the meta-analyses. In the first analysis, we examined the effects of single-session tDCS across all language studies. Next, a series of sub-analyses examined the effects of tDCS on specific tasks and stimulation protocols.
resultsThere was a significant effect from anodal single-session tDCS in healthy adults compared to sham (P = 0.001) across all language measures. Next, we found significant effects on specific stimulation protocols (e.g., offline measures, P = 0.002), as well as specific tasks and electrode montages (e.g., verbal fluency measures and left prefrontal cortex, P = 0.035).
conclusionsThe results indicate that single-session tDCS produces significant and reliable effects on language measures in healthy adults.
