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

This case report presents a common but instructive clinical scenario of accidental ingestion of a press-through package. Despite an initial negative chest X-ray and mild symptoms, the diagnosis was confirmed with additional computed tomography. The patient was eventually went through the successful endoscopic removal of the press-through package. Furthermore, a retrospective re-reviewing of the X-ray revealed a faint ring-shaped gas sign, characteristic of press-through package ingestion. This case underscores the intractableness to diagnosis of accidental ingestion of press-through package by only X-rays in real time and the potential role of computed tomography in ensuring timely diagnosis and treatment.
