1 · What the graph read from it

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.

2 · The registry

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

backgroundCrohn's disease (CD) is a chronic inflammatory disorder belonging to the inflammatory bowel diseases (IBD). CD affects distinct parts of the gastrointestinal tract, leading to symptoms including diarrhea, fever, abdominal pain, weight loss, and anemia. The aim of this study was to assess whether the DNA methylome of peripheral blood cells can be associated with CD in women.

methodsSamples were obtained from 18 female patients with histologically confirmed ileal or ileocolic CD and 25 healthy age- and gender-matched controls (mean age and standard deviation: 30.5 ± 6.5 years for both groups). Genome-wide DNA methylation was determined using the Illumina HumanMethylation 450k BeadChip.

resultsOur analysis implicated 4287 differentially methylated positions (DMPs; corrected p < 0.05) that are associated to 2715 unique genes. Gene ontology enrichment analysis revealed significant enrichment of our DMPs in immune response processes and inflammatory pathways. Of the 4287 DMPs, 32 DMPs were located on chromosome X with several hits for MIR223 and PABPC5. Comparison with previously performed (epi)genome-wide studies revealed that we replicated 33 IBD-associated genes. In addition to DMPs, we found eight differentially methylated regions (DMRs).

conclusionsCD patients display a characteristic DNA methylation landscape, with the differentially methylated genes being implicated in immune response. Additionally, DMPs were found on chromosome X suggesting X-linked manifestations of CD that could be associated with female-specific symptoms.
