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
backgroundThe long noncoding RNA, NEAT1, is recognized as a key regulator of proinflammatory gene expression; Yet, its functional role in migraine remains unexplored, despite the central role of neuroinflammatory mechanisms in migraine pathophysiology. This study examines the implication of NEAT1 in the trigeminal ganglion activation, which underlies photophobia associated with migraine.
methodsLight aversion behavior was induced by intranasal injection of the TRPA1 activator, umbellulone. Male mouse behavior was assessed by the total time the mouse stays in the light between the dark and light compartments. To gain insight to the NEAT1-mediated photophobia mechanism, gene expression of candidate genes and non-coding RNAs interactions were assessed using RNA-sequencing, qPCR analysis, histology and dual-luciferase reporter gene assay.
resultsNEAT1 was upregulated in the trigeminal ganglion of male photophobia mice; Downregulation of NEAT1 by intravenous injection of shNEAT1 adeno-associated virus vectors attenuated NEAT1 expression and alleviated photophobia-like behavior in mice. The elevated NEAT1 expression in the trigeminal ganglion of photophobia mice corresponds to the downregulation of miR-196a-5p and upregulation Trpm3 RNA level. Predicted analysis suggested NEAT1/miR-196a-5p ceRNA network exists in photophobia mice. Indeed, knocking down NEAT1 upregulated miR-196a-5p, whilst downregulated Trpm3 gene expression level, in the trigeminal ganglion of photophobia mice. Further investigation using dual-luciferase reporter gene assay identified NEAT1 interacting with miR-196a-5p, whilst miR-196a-5p interacting with Trpm3. Similar to knocking down NEAT1, TRPM3 inhibition reduced photophobia-like behavior.
conclusionWe conclude that NEAT1 is critical for promoting photophobia behavior via miR-196a-5p/Trpm3 coupling.
