Prevalence of Functional GI Diseases and Pelvic Floor Symptoms in Marfan Syndrome and Ehlers-Danlos Syndrome: A National Cohort Study.

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
aimsPrior studies have shown a high prevalence of gastrointestinal (GI) symptoms, diagnoses of functional GI diseases (FGIDs), and pelvic floor symptoms associated with Ehlers-Danlos syndrome (EDS). It is unclear if Marfan syndrome (MFS), another common hereditary noninflammatory connective tissue disorder, is also associated these symptoms. This study evaluates the prevalence of and compares FGIDs and pelvic floor symptoms in a national cohort of EDS and MFS patients.
methodsA questionnaire was sent to members of local and national MFS and EDS societies. The questionnaire evaluated the presence of GI and pelvic floor symptoms and diagnoses. The presence of FGIDs was confirmed using Rome III criteria. Quality of life was evaluated and scored with the CDC quality of life. KEY
resultsOverall, 3934 patients completed the questionnaire, from which 1804 reported that they had some form of EDS and 600 had MFS. In total, 93% of patients with EDS complained of GI symptoms and qualified for at least one FGID compared with 69.8% of patients with MFS. When comparing EDS prevalence of upper and lower GI symptoms as well as FGIDs, subjects with EDS reported significantly higher prevalence of Rome III FGIDs as compared with those with MFS. Irritable bowel syndrome (57.8% vs. 27.0%, P<0.001), functional dyspepsia (FD) (55.4% vs. 25.0%, P<0.001), postprandial distress (49.6% vs. 21.7%, P<0.001), heartburn (33.1% vs. 16.8%, P<0.001), dysphagia (28.5% vs. 18.3%, P<0.001), aerophagia (24.7% vs. 12.3%, P<0.001), and nausea (24.7% vs. 7.2%, P<0.001) were all significantly greater in the EDS population compared with MFS population. The prevalence of FGIDs was similar across subtypes of EDS. In general, participants with EDS were more likely to have nearly all pelvic floor symptoms as compared with participants with MFS.
conclusionsThe prevalence of FGIDs and pelvic floor symptoms in EDS is higher than that found in MFS. The prevalence of FGIDs were similar across EDS subtypes. This study supports the mounting evidence for FGIDs in those with connective tissue diseases, but more specifically, in EDS.
