A Bamboo Joint-Like Appearance is a Characteristic Finding in the Upper Gastrointestinal Tract of Crohn's Disease Patients: A Case-Control Study.

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 clinical importance of Crohn's disease (CD)-specific lesions in the upper gastrointestinal tract (upper GIT) has not been sufficiently established. The aim of this case-control study is to investigate the characteristic findings of CD in the upper GIT. In 2740 patients who underwent gastroduodenoscopy at Asahikawa Medical University between April 2011 and December 2012, 81 CD patients, 81 gender- and age-matched non-IBD patients, and 66 ulcerative colitis (UC) patients were investigated in the present study. (1) The diagnostic ability and odds ratio of each endoscopic finding (a bamboo joint-like appearance in the cardia, erosions, and/or ulcers in the antrum, notched signs, and erosions and/or ulcers in the duodenum) were compared between the CD and non-IBD patients or UC patients. (2) The interobserver agreement of the diagnosis based on the endoscopic findings was evaluated by 3 experienced and 3 less-experienced endoscopists. The incidence of detecting a bamboo joint-like appearance, notched signs, and erosions and/or ulcers in the duodenum was significantly higher in the CD patients than in the non-IBD and UC patients. In addition, the diagnostic ability and odds ratio of a bamboo joint-like appearance for CD were higher than those for the other findings. Kendall's coefficients of concordance in the group of experienced and less-experienced endoscopists were relatively high for a bamboo joint-like appearance (0.748 and 0.692, respectively). A cardiac bamboo joint-like appearance is a useful finding for identifying high-risk groups of CD patients using only gastroduodenoscopy.
