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

Hypothermic cardiac arrest (HCA) is often caused by ventricular tachyarrhythmias in severe hypothermia. The QRS/QTc ratio may predict arrhythmia risk, but data are insufficient. Routine QRS/QTc measurements during transport and in-hospital care, along with consistent reporting, could improve understanding, management, and survival outcomes in severe accidental hypothermia cases.
