Learning curve for endoscopic submucosal dissection in early gastric neoplasm using a multibending endoscope.
Article in Therapeutic advances in gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Background: Endoscopic submucosal dissection (ESD) is a representative treatment modality for early gastric neoplasms. However, the learning curve for beginners performing ESD using a multibending endoscope has not been introduced. Objective: This study aimed to evaluate the learning curves of operators undergoing intensive training using a multibending endoscope. Design: This was a retrospective single center study. Methods: We retrospectively analyzed data of over 1500 consecutive gastric ESDs performed by two operators using a multibending endoscope. A change-point analysis with 50 cases of moving average speeds was used to determine the new target resection speed. Cumulative sum (CUSUM) analysis was used to identify the cases required for proficiency in ESD. Risk-adjusted CUSUM (RA-CUSUM) analysis was performed for each operator after adjusting for confounding factors influencing the resection speed. Results: In total, 1491 cases were enrolled, with early gastric cancer accounting for 43.2% ( Conclusion: Using a multibending endoscope for gastric ESD can help beginners achieve safe and excellent outcomes. These findings will serve as a useful guide for beginners attempting to use a multibending endoscope.
