"Partial Annular Pancreas Causing Obstruction of the First Part of the Duodenum: An Exceedingly Rare Conundrum-A Rare Case Report and Comprehensive Literature Review".
Article in Clinical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
The annular pancreas is one of the very few congenital anomalies associated with gastric outlet obstruction. Usually, it is associated with obstruction of the second part of the duodenum, but to the authors' knowledge, this is the first reported case of the partial annular pancreas obstructing the first part of the duodenum, leading to late presentation of gastric outlet obstruction. As clinicians, we should be vigilant about the causes of abdominal fullness and pain and consider the annular pancreas an important differential diagnosis. It also challenges our predetermined concept of obstruction of the second part of the duodenum secondary to the annular pancreas. Even though the annular pancreas rarely obstructs the first part of the duodenum, it should always be kept in the back of our mind while diagnosing and managing elderly patients presenting with features of gastric outlet obstruction. This paper highlights the atypical presentation of the annular pancreas and how appropriate radiological investigation can clinch the uncommon diagnosis and help in the appropriate management.
