Transcranial direct current stimulation for enhancing attention following mild traumatic brain injury: a narrative review.
Review in Frontiers in neurology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Attention deficits often persist after mild traumatic brain injury (mTBI), limiting recovery despite normal imaging. Transcranial direct current stimulation (tDCS) has emerged as a non-invasive therapeutic option. Aims: This review evaluates the evidence supporting tDCS as a method to improve attention in individuals with mTBI or post-concussive symptoms. Methods: Peer-reviewed studies focusing on attentional outcomes after tDCS in mTBI were examined. Related findings from ADHD and mild cognitive impairment were included where relevant. Results: Most protocols used anodal tDCS targeting the left dorsolateral prefrontal cortex (2 mA for ~20 min across multiple sessions). Reported benefits included improved sustained attention, quicker response times, and enhanced cognitive control, particularly when paired with cognitive exercises. Neurophysiological markers often reflected behavioral gains, though most trials were small and lacked follow-up. Conclusion: While preliminary results are encouraging, larger and standardized trials are essential before routine clinical use.
