Endoscopic ultrasound assessment of gastrointestinal polypoid lesions of indeterminate morphology in patients with portal hypertension.
Article in Endoscopy international open, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 STUDY
aimsPolypoid lesions found during upper gastrointestinal endoscopy (UGIE) are occasionally found in patients with portal hypertension (PH). This study aimed to assess the true nature of such polypoid lesions using endoscopic ultrasound (EUS) and determine the accuracy of UGIE in differentiating between vascular and non-vascular lesions in PH. PATIENTS AND
methodsWe retrospectively assessed all patients with PH referred for EUS due to polypoid lesions of unknown nature at UGIE over a 7-year period. Cases of known varices were excluded. UGIE findings were compared to EUS findings.
results66 patients were included (26 male). Commonest UGIE findings were: possible varices (19.4 %), polypoid/neoplastic lesion (52.8 %) and submucosal lesion (16.7 %). After EUS, the final diagnoses were: varices in 25 %, polypoid lesion with underlying vessel/varix in 27.8 % and non-vascular lesion or submucosal lesion in 47.2 %. The diagnostic accuracy of UGIE was suboptimal, since 28.6 % of possible varices were eventually found to be non-vascular, while 15.8 % of polyp/neoplastic looking lesions proved to be varices and 42.1 % were lesions with underlying vessel/varix. 50 % of submucosal lesions were eventually found to be varices.
conclusionEndoscopists should have a high index of suspicion of varices or polyps related to varices when assessing atypical looking polypoid lesions in patients with PH. In such cases EUS should be considered before obtaining biopsies.
