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

Dysphagia is an uncommon presenting symptom of lung cancer, occurring in a minority of patients and often leading clinicians to pursue gastrointestinal etiologies first. However, thoracic malignancies, particularly small cell lung carcinoma (SCLC), may occasionally present with esophageal symptoms due to mediastinal involvement. Upper endoscopy and upper endoscopic ultrasound play a role in patients with esophageal extrinsic compression and/or local invasion. Herein, we describe a case of a 29-year-old man with no history of tobacco use who presented with progressive dysphagia and significant weight loss and was diagnosed with small-cell lung cancer.
