Modulatory effects of transcranial direct current stimulation on sensory gating in Fibromyalgia Syndrome.
Article in Frontiers in psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Introduction: Several studies have demonstrated a reduced habituation to redundant somatosensory stimulation (sensory gating) in Fibromyalgia Syndrome. Furthermore, anodal transcranial direct current stimulation has been shown to modulate somatosensory processing. The aim of this study was to examine the modulatory effects of anodal transcranial direct current stimulation applied over the left primary somatosensory cortex on sensory gating in Fibromyalgia Syndrome. Methods: Thirty-nine female Fibromyalgia Syndrome patients (43-71 years, mean 55.56 ± 7.85) participated in the study and were randomly assigned to the active transcranial direct current stimulation ( Results: Whereas P50 and N100 components were unaltered, a significant modulatory effect on the difference S1 - S2-which is commonly considered an index of sensory gating-in the Late Positive Complex component was found. This modulation manifested as an increased difference in the right hemisphere (contralateral to the stimulation) and a decreased difference in the left hemisphere (ipsilateral). Discussion: Although this lateralizing pattern remains to be clarified, present results suggest brain excitability and somatosensory processing modulation by using anodal transcranial direct current stimulation in Fibromyalgia Syndrome patients.
