Small-Bowel Angioectasias: Are They Responsible for a Real Impact on Survival?
Article in GE Portuguese journal of gastroenterology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
Introduction: This study aimed to evaluate the effect of small-bowel angioectasia on survival, given the hypothesis that angioectasia might be an independent risk factor of frailty and poor outcomes. Methods: In this retrospective cohort study, all patients undergoing small-bowel capsule endoscopy between 2010 and 2013 for obscure gastrointestinal bleeding from a Portuguese tertiary centre were included. Follow-up started after capsule endoscopy and ended upon death or end of the study (November 2020). Survival analysis was performed using a Cox proportional-hazards model, in order to analyse the effect of small-bowel angioectasia on survival as well as potentially confounding factors (age, vascular diseases and chronic kidney disease). Results: A total of 176 patients were included in this study (50.6% male), with a median age of 68.5 years (IQR 24). The median follow-up was 7 years (IQR 4), during which 67 (38.1%) patients died. Seventy-three (41.5%) patients had at least one small-bowel angioectasia on capsule endoscopy. On multivariate Cox regression analysis, only age, peripheral arterial disease, history of previous mesenteric ischaemia and chronic kidney disease were independent risk factors of death. The presence of small-bowel angioectasia did not affect survival in this analysis (HR 1.30; 95% CI 0.75-2.23; Conclusion: In this retrospective cohort study, some comorbidities and age were independent predictors of poor survival. The presence of small-bowel angioectasia per se did not affect survival.
