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

We report a case of a 70-year-old woman with esophageal achalasia and concurrent superficial esophageal squamous cell carcinoma. Three adjacent superficial lesions were resected en bloc by endoscopic submucosal dissection (ESD), with no lymphovascular invasion. Given that the patient's dysphagia was effectively controlled with medication and dietary modifications, peroral endoscopic myotomy (POEM) was deferred following a careful assessment of the risk-benefit balance. As both ESD and POEM involve submucosal intervention, this case highlights the importance of individualized treatment based on symptom severity and lesion characteristics.
