1 · What the graph read from it

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.

2 · The registry

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 AND

aimsColorectal endoscopic submucosal dissection (ESD) presents persistent challenges such as limited visualization and prolonged procedure time. Single-point traction (ST) enhances dissection efficiency, but has limitations including diminished traction efficacy over time and the need for repositioning. We developed a novel multi-point traction (MT) device to provide stable and convergent traction. This study aimed to compare the efficacy and safety of non-traction (NT), ST, and MT for colorectal ESD.

methodsThis retrospective study analyzed colorectal ESD procedures performed at Nagasaki Harbor Medical Center between January 2019 and December 2024. The patients were categorized into three groups: NT, ST (S-O clip), and MT (novel multi-point traction device). The primary outcome was resection speed (mm

resultsA total of 172 patients were eligible (NT 62, ST 67, MT 43), and after applying the exclusion criteria, 129 remained (NT 43, ST 51, MT 35) for the analyses of procedural parameters. The MT group achieved the highest resection speed (23.8 [IQR 18.9-33.2] mm

conclusionsMulti-point traction may improve resection efficiency, while maintaining safety during colorectal ESD. Future prospective multicenter trials are required to validate these findings and optimize the traction strategies.
