Comparison of Risk Factors Between Small Intestinal Ulcerative and Vascular Lesions in Occult Versus Overt Obscure Gastrointestinal Bleeding.
Article in Digestive diseases and sciences, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
BACKGROUND AND
aimsThe detailed risk factors such as bleeding pattern, comorbidities, and medication usage of patients with obscure gastrointestinal bleeding (OGIB) are largely unknown. We evaluated the risk factors related to ulcerative and vascular lesions of the small intestine diagnosed by capsule endoscopy or balloon-assisted endoscopy in OGIB cases.
methodsWe retrospectively evaluated 390 OGIB cases (occult, n = 101; overt, n = 289) in our hospital between January 2005 and March 2011 using univariate and multivariate logistic regression analyses to determine the related risk factors.
resultsIn occult (n = 36) and overt (n = 120) OGIB cases, some lesions were detected in the small intestine. Ulcerative and vascular lesions were detected in both occult (n = 25, 69.4 %; n = 8, 22.2 %, respectively) and overt (n = 57, 47.5 %; n = 39, 32.5 %, respectively) cases. For ulcerative lesions, non-steroidal anti-inflammatory drugs were identified as a risk factor in overt cases [odds ratio (OR) 2.974, 95 % confidence interval (CI) 1.522-5.809, P = 0.001]. For vascular lesions, lowest hemoglobin level (OR 0.634, 95 % CI 0.422-0.953, P = 0.028) and hematologic disease (OR 8.575, 95 % CI 1.076-68.309, P = 0.042) were identified as risk factors in occult cases, whereas hemodialysis (OR 3.71, 95 % CI 1.315-10.467, P = 0.013) was identified in overt cases. Additionally, liver cirrhosis was noted as a risk factor in both occult (OR 7.453, 95 % CI 1.213-45.773, P = 0.013) and overt (OR 4.900, 95 % CI 2.099-11.443, P < 0.001) OGIB cases.
conclusionThere are differences in risk factors related to ulcerative versus vascular lesions in the small intestine in occult and overt OGIB cases. Differences were seen in both medication usage and comorbidities.
