Motility index measured by magnetic resonance enterography is associated with sex and mural thickness.

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
backgroundRecently, a technique has been developed to use magnetic resonance enterography (MRE) for the evaluation of small bowel motility. The hypothesis was that assessment of the motility index (MI) should reflect differences in motility between clinical conditions.
aimTo aim of the present observational, cross-sectional study was to evaluate the use of the MI in daily clinical practice.
methodsAll consecutive patients aged 18-70 years who were referred for MRE at the Department of Radiology during a 2-year period were asked to participate. Healthy volunteers were included as controls. MRE was prepared and conducted in accordance with clinical routines. On the day of examination, all the participants had to complete the visual analog scale for irritable bowel syndrome (IBS) and IBS-symptom severity scale. Maps of MI were calculated from dynamic MR images. ANOVA was used to evaluate differences in MI between groups, classified as healthy, Crohn's disease, ulcerative colitis, IBS, other assorted disorders and dysmotility. Logistic and linear regression were applied to the MI values. All medical records were scrutinized for medical history.
resultsIn all, 224 examinations were included (inclusion prevalence 76.3%), with 22 controls and 202 patients. There was a significant difference in the MI of the jejunum (
conclusionAlthough MIs differ across diseases, a lower MI of the terminal ileum is mainly associated with male sex and an increased mural thickness. Symptoms are weakly associated with the MI.
