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: Small bowel bleeding accounts for about 5%-8% of all cases of gastrointestinal bleeding. Suspected small bowel bleeding (SSBB) can be classified into occult, inactive overt, and overt. Most patients with SSBB will undergo balloon-assisted enteroscopy (BAE) for diagnosis and treatment. There are currently no recommendations from practice guidelines on what is the best approach and limited information about diagnostic and therapeutic yields for each subtype of SSBB. Aims and Methods: We aimed to investigate the diagnostic and therapeutic yields of BAE in the 3 subtypes of patients with SSBB by performing a retrospective analysis of all patients that underwent BAE for this diagnosis at the University of Alberta Hospital in a 5-year period. We also aimed to identify other factors that could influence diagnostic and therapeutic yields. Results: The overall diagnostic and therapeutic yields of BAE for SSBB were 66% and 51%, respectively. When stratified by subtypes of SSBB, the diagnostic yield for occult, inactive overt, and active overt SSBB were reported to be 61%, 67%, and 95% ( Conclusions: Our data showed the clinical differences between the 3 subtypes of patients with SSBB and the usefulness of an appropriate and timely approach to maximize the diagnostic and therapeutic yields.
