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
Attentional reorientation is crucial to navigating the world and relies heavily on the parietal cortex. Several studies have shown that transcranial direct current stimulation (tDCS) has an effect on attentional reorientation; however, these studies mainly focused on the difference between anodal and cathodal stimulation. In this study, we investigated the role of left versus right inferior parietal cortices in attention reorientation by applying high-definition tDCS (HD-tDCS) to these regions in 39 healthy adults (age 19-33 years) for 20 minutes in 3 separate sessions (left active, right active, and sham). Following stimulation, participants completed a modified Posner task during magnetoencephalography (MEG). Significant neural responses at the sensor level across all conditions were then imaged using a beamformer, and the whole-brain, voxel-wise maps were probed for task condition and stimulation montage effects. Our neural findings showed significant stimulation montage by task condition interactions that were multispectral and involved the left frontal eye fields, right inferior parietal cortex, and left anterior prefrontal cortex. We also observed main effects of stimulation montage in the theta and beta ranges, main effects of task condition that were consistent with previous studies of attentional reorienting, and a significant neurobehavioral relationship between theta oscillations in the left frontal eye fields and accuracy. Overall, our findings indicate that HD-tDCS of the inferior parietal cortices modulates several brain regions that are important for attentional reorientation.
