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
Inter-brain synchrony, the co-activation of brain regions between interacting individuals, is increasingly recognized as a key mechanism underlying social connectedness. This study examined whether dyadic neurofeedback training can enhance inter-brain synchrony in the inferior frontal gyrus and causally increase connectedness. We developed a real-time dyadic neurofeedback platform using functional near-infrared spectroscopy, where unacquainted dyads underwent three training sessions receiving either real neurofeedback or sham feedback. Although we initially anticipated a gradual increase across sessions, the neurofeedback group showed a significant enhancement in IFG inter-brain synchrony only in the third session, with effects extending to additional regions. These neural changes coincided with increased feelings of connectedness and shifts in intra-brain co-activation. While the precise strategies underlying dyadic regulation remain unclear, and additional sessions are needed to fully characterize the learning trajectory, the present findings provide preliminary evidence for the plasticity of inter-brain synchrony and its potential relevance for improving social outcomes.
