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

Nitrous oxide, known as "laughing gas," is a substance that can be used to induce analgesia and euphoria. It is easily accessible in certain household products, such as aerosol canisters used for food products. However, chronic use of nitrous oxide can inhibit cobalamin (vitamin B12), causing severe deficiencies that result in psychiatric, hematologic, and neurological toxicities, including subacute combined degeneration of the spinal cord. We present a case of a young adult male who developed progressive, ascending bilateral paresthesias and gait disturbances, ultimately attributed to nitrous oxide use. This case highlights the neurotoxic effects and symptoms associated with recreational nitrous oxide use, as well as the patient's treatment and subsequent clinical recovery.
