Auditory gating and its clinical correlates in adults with chronic tic disorder and neurotypical adults.

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
backgroundOver 80% of adults with chronic tic disorder (CTD) experience sensory over-responsivity (SOR), defined as heightened awareness of and/or behavioral reactivity to commonplace environmental stimuli. One potential mechanism underpinning SOR is sensory gating impairment. Sensory gating is the physiologic process whereby redundant stimuli are filtered out in early perceptual stages. In this study, we compared sensory gating between neurotypical and CTD adults and determined if gating indices associated with SOR.
methodsNeurotypical (n = 31) and CTD adults (n = 26) completed a clinical assessment, including two SOR measures (Sensory Gating Inventory, SGI; Sensory Perception Quotient, SPQ), and an auditory gating paradigm while monitored on EEG.
resultsCTD adults exhibited greater SOR. Neurotypical and CTD adults did not differ in P50, N100, or P200 gating ratios. In regression analyses, N100 gating ratio was significantly associated with SGI score; the magnitude of this association was greater for neurotypical than CTD adults. No other significant associations emerged between gating ratios and SOR measures.
conclusionFindings do not support sensory gating impairment as a mechanism underpinning SOR in CTD. The relationship between N100 gating and SOR warrants further investigation. SIGNIFICANCE: This is the first study to examine auditory gating in individuals with CTD.
