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

In endoscopic full-thickness resection (EFTR), luminal collapse can occur due to communication between the gastrointestinal lumen and peritoneal cavity, making visualization and procedural continuity difficult. We propose the underwater pressure lumen expansion (UPLE) method, in which hydraulic pressure is applied in a fluid-filled environment to re-expand the collapsed lumen, thereby restoring visualization and allowing continued endoscopic manipulation. The UPLE method was applied during peroral endoscopic tumor resection in a clinical case and in an animal model of EFTR, and its utility was successfully demonstrated.
