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

Endoscopic submucosal dissection (ESD) for pharyngeal squamous cell carcinoma (SCC) has predominantly been performed in Asia but interest in this procedure is growing in the West. This report details the first known Western application of ESD for oropharyngeal SCC. A Caucasian female with superficial oropharyngeal SCC detected during endoscopic surveillance post-ESD for esophageal SCC underwent successful en-bloc resection without complications. Pathology confirmed SCC in situ with tumor-free margins. This case underscores the importance of mindset to include the pharynx in upper gastrointestinal endoscopy during surveillance within the gastroenterologist's domain and the potential for broader application of ESD in the West.
