Altered expression of KCNG3 and KCNG4 in Hirschsprung's disease.
Article in Pediatric surgery international, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeVoltage-gated potassium ion channels have long been implicated in gastrointestinal motility. Recent studies have highlighted the role of voltage-gated channel subfamily G member 3 (KCNG3) and 4 (KCNG4) genes in the electrical functioning of interstitial cells of Cajal and PDGFRα
methodsHSCR tissue specimens (n = 6) were collected at the time of pull-through surgery, while control samples were obtained at the time of colostomy closure in patients with imperforate anus (n = 6). qRT-PCR analysis was undertaken to quantify KCNG3 and KCNG4 gene expression, and immunolabelling of KCNG3 and KCNG4 proteins was visualized using confocal microscopy.
resultsqRT-PCR analysis revealed significant downregulation of the KCNG3 and KCNG4 genes in both aganglionic and ganglionic HSCR specimens compared to controls (p < 0.05). Confocal microscopy revealed KCNG3 and KCNG4 expression within neurons, ICC and PDGFRα
conclusionKCNG3 and KCNG4 gene expression is significantly downregulated in HSCR colon, suggesting a role for these genes in colonic motility. KCNG3 and KCNG4 downregulation within ganglionic specimens highlights the physiologically abnormal nature of this segment in HSCR patients.
