Effect of cigarette smoke extract on the intestinal microenvironment of ulcerative colitis tissue.

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
BACKGROUND AND
aimUlcerative colitis (UC) is an autoimmune disease characterized by inflammation in the gastrointestinal tract. The severity of UC is higher in nonsmokers than smokers; however, the biological mechanisms controlling this effect remain unknown. The aim of this study was to examine the effect of cigarette smoke extract (CSE) on inflamed and noninflamed colonic tissue from UC patients and to determine if inflammatory mediators, transcription factors, and T cell phenotypes are altered by CSE.
methodsBlood and colonic biopsies were obtained from UC patients undergoing endoscopy. Biopsies were cultured in the presence or absence of CSE. Multiplex enzyme-linked immunosorbent assay (ELISA) measured secreted levels of inflammatory mediators. Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and Hypoxia-inducible factor 1-alpha (HIF-1α) expression were measured by DNA-binding ELISA. T cell phenotypes were assessed by flow cytometry in matched blood and biopsies.
resultsSecreted levels of interleukin 2 (IL-2), interleukin 6 (IL-6), tumor necrosis factor - alpha (TNF-α), chemokine (C-C motif) ligand 2 (CCL2), and interleukin 10 (IL-10) were significantly (all
conclusionThese data suggest that observed effects of CSE in reducing inflammatory mediators
