Examination of endoscopic intracanal observation with an ultrafine-diameter scope.
Article in DEN open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: The endoscopic channel can be damaged by instruments during use and cleaning, leading to contamination, infection, and increased repair costs. However, few devices are available to observe the inside of the endoscopic channel. This study employed an ultrafine-diameter scope to examine damage in the endoscopic channel. Methods: Fifty-eight endoscopes used at our institution were examined for scratches, discoloration, or deformation in the endoscopic channel using an ultrafine-diameter scope. Results: Damage was observed in seven of the 24 observation endoscopes and 27 of the 34 therapeutic endoscopes, with damage being more common in the therapeutic endoscopes. Scratches were observed in nine of the 25 upper gastrointestinal endoscopes, 23 of the 24 colonoscopes, and one of the two echoendoscopes. Additionally, two colonoscopes, one echoendoscope, and one double-balloon endoscope showed indentation or narrowing near the curvature. Conclusions: The use of an ultrafine-diameter scope enabled the detection of minute damage and deformations in the channel. Periodic observation with the ultrafine-diameter scope may promote the long-term use of the scopes.
