Association of Crohn's disease with Foxp3 gene polymorphisms and its colonic expression in Chinese patients.
Article in Journal of clinical laboratory analysis, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundFork head/winged helix transcription factor (Foxp3) plays a pivotal role in regulatory T (Treg) cells. The present study aimed to assess the association of Crohn's disease (CD) with Foxp3 polymorphisms and its colonic expression in Chinese patients.
methodsThe Foxp3 polymorphisms, rs3761547, rs2232365, rs2294021, and rs3761548, were examined by SNaPshot in 268 CD patients and 490 controls. The colonic expression levels of Foxp3, IL-2, and IL-4 were detected in 31 CD patients and 31 controls using real-time quantitative polymerase chain reaction, immunohistochemistry, and enzyme-linked immunosorbent assay.
resultsCompared to male controls, the proportion of variant allele of rs3761547 was increased in male patients. The variant alleles of rs3761547, rs2232365, and rs2294021 were less in male patients with stricturing CD compared to those with non-stricturing, non-penetrating CD; however, these variants were frequently detected in male patients with colonic CD than in those with ileocolonic CD. The variant allele of rs3761548 was increased in male patients with penetrating CD compared to those with non-stricturing, non-penetrating CD. The colonic expression of Foxp3 was higher in CD patients than in controls (both males and females). Compared to male patients carrying wild-type alleles, the colonic expression of Foxp3 was downregulated in male patients with variant alleles, rs3761547, rs2232365, rs2294021, and rs3761548, respectively. However, the Foxp3 polymorphisms were not significantly related with the colonic expression levels of IL-2 and IL-4 in CD patients (both males and females).
conclusionFoxp3 polymorphisms might increase the CD susceptibility by reducing the colonic expression of Foxp3 in male patients.
