Enhancing spatial reasoning by anodal transcranial direct current stimulation over the right posterior parietal cortex.
Article in Experimental brain research, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Spatial reasoning is essential for an agent's navigation and the cognitive processing of abstract arrangements. Meta-analyses of neuroimaging data reveal that both the right posterior parietal cortex and left dorsolateral prefrontal cortex (PPC and DLPFC, respectively) show increased activation during spatial relational reasoning. To investigate whether participants' reasoning performance can be modified and potentially enhanced, anodal transcranial direct current stimulation (tDCS) was applied over either region. 51 healthy adult participants solved spatial reasoning problems after the application of either anodal tDCS over the right PPC, the left DLPFC or a sham stimulation. We expect anodal stimulation to enhance cortical excitability which would be reflected by enhanced reasoning performance in participants receiving stimulation. The results demonstrate that anodal stimulation applied over the right PPC enhances participants' performance in indeterminate reasoning problems, compared to sham and anodal stimulation over the left DLPFC. This finding is highly relevant for clarifying the cognitive mechanisms of relational reasoning and for clinical applications, e.g., enhancing or restoring higher cognitive functions for spatial representation and reasoning.
