Orthodontic rubber band combined with magnetic ring as a traction device for improving endoscopic submucosal dissection training.
Article in BMC medical education, 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
backgroundGood exposure of the submucosal visual field is a prerequisite for successful endoscopic submucosal dissection (ESD). There are few reports on ESD training using orthodontic rubber band combined with magnetic ring traction (ORB-MR). This study evaluated the efficacy of ORB-MR traction for ESD training.
methodsThis study utilized an ex vivo porcine gastric model. Doctors experienced in endoscopic mucosal resection (> 100 cases), but not in ESD, were randomly divided into conventional and ORB-MR-assisted ESD groups. The practicality of ORB-MR traction was evaluated and procedure outcomes were compared between the two groups. The cumulative sum (CUSUM) method was used to construct the learning curves of ORB-MR and traditional ESD trainees respectively.
resultsA questionnaire survey of the ORB-MR-ESD group showed good satisfaction with ORB-MR. Per-Protocol analysis showed that the resection speed was faster in the ORB-MR group compared to the ESD group (11.61 ± 3.79 mm
conclusionsORB-MR traction proved feasible and practical for ESD. It shortened the learning curve for ESD trainees and exhibited potential as a valuable method for ESD training.
