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

An 18-year-old male driving an off-road motorcycle died from complete decapitation when his motorcycle tore a roadblock chain from its attachment. The decapitation injuries of the head and the torso corresponded perfectly, without apparent loss of tissue. The severance plane passed horizontally through the upper cervical region and C4, which sustained a comminuted fracture. The sharply delineated severance edge had a band-like abrasion. The decapitation resulted from the rotational movement of the unstrung chain, which struck and strangled the driver's neck. We were able to explain the movement of the chain and the decapitation mechanism. This case emphasizes the importance of discussing dynamics with experts to clarify a causal mechanism.
