The utilisation and diagnostic yield of radiological imaging in a specialist functional GI disorder clinic: an 11-year retrospective study.
Article in European radiology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThe term functional gastrointestinal disorders (FGID) describes various aggregations of chronic gastrointestinal (GI) symptoms not explained by identifiable organic pathology; accordingly, their diagnosis rests on symptom-based criteria and a process of exclusion. Evidence is lacking on the appropriate use of abdominal imaging studies (AIS) in FGIDs.
methodsWe investigated the utilisation of AIS (site, modality, diagnostic yield/significance) at a tertiary FGID clinic over an 11-year period.
resultsOf 1,621 patients, 507 (31%; 67.5% women, mean age 43.9 ± 17.37 years) referred from primary care had 997 AIS (1.7 per patient): ultrasonography (US) 36.1%, fluoroscopy (FLS) 28.8%, computed tomography (CT) 19.6%, plain radiography (PR) 13.5%, nuclear medicine (NM) 1%). Of the 997 AIS, 55.6% (554/997) were normal. Of the AIS with positive findings, 9.9% (62/625) were deemed 'probably significant' and 14.7% (92/625) 'significant'. Of the CT and FLS studies, 12.3% and 13.6%, respectively, yielded 'significant' abnormalities compared to 2.2% of the US studies and 2.1% of the PR studies. CT identified five of seven neoplasms, associated with male sex, increasing age and symptom onset after age 50 years.
conclusionsThis study confirmed low use of AIS in tertiary FGID clinics and a high proportion of normal studies. Barium swallow/meal and CT were more likely to identify 'probably significant' or 'significant' findings, including neoplasms. KEY POINTS: Imaging referral rates from a specialist functional gastrointestinal disorder clinic are low. Despite this, normal studies are still frequent in those who are imaged. Ultrasonography was the most frequent investigation, yet yielded significant findings infrequently. Abdominal radiographs accounted for 13.5% of investigations yet were normal in 71.8 %. CT and fluoroscopy were more likely to yield positive findings.
