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 describes a fatal case of sodium nitrite and multiple drug consumption. A 37-year-old female was found in bed with a plastic bottle containing sodium nitrite and a bag containing multiple drugs and a suicide note. The results of the autopsy showed completely fixed grayish livor mortis, signs of asphyxia on the lips, and facial cyanosis. This represents the second case in just a few months and highlights how relatively easy it is to buy sodium nitrite to commit suicide, indicating that specific responses should focus on restricting its access, especially in large quantities. It was also evident that the number of web forums and shadow markets explaining how to use sodium nitrite for euthanasia (several times called the "exit") are increasing.
