1 · What the graph read from it

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.

2 · The registry

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

purposeThe aim was to study visual perception changes based on eye-tracking data assessments in response to transcranial photobiomodulation (t-PBM) in young, healthy subjects. MATERIAL AND

methodsOur non-randomized single-center study involving 53 young, healthy volunteers (22 men and 31 women). The eye tracking procedure (EyeTracker, BVG Software Group LLC, CA, USA) was carried out before and immediately after t-PBM (Elmedlife H, RF). Data were expressed as a median [interquartile range]. Statistical analysis was performed using the T- criterion Wilcoxon. The significance level was preset p < 0.05.

resultsVertical vergence reactivity indexes (VRx) after t-PBM were significantly higher than before 0.881 [0.841; 0.914] vs. 0.784 [0.711; 0.832], p < 0.05, respectively. Horizontal VRx before t-PBM were significantly lower than after t-PBM 0.893 [0.822; 0.935] vs. 0.920 [0.917; 0.929], p < 0.05.

conclusionTranscranial PBM improves visual perception in young, healthy volunteers, as reflected by a significant increase in both vergence reactivity indices.
