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

introductionKetamine, a commonly used medication to treat agitation, has known adverse effects such as emergence reactions, vomiting, and laryngospasm. Opisthotonos has not been a commonly reported adverse reaction. CASE REPORT: We report a case of opisthotonos brought on by administration of ketamine. A 24-year-old male with a history of schizophrenia was brought in by emergency medical services with opisthotonos shortly after treatment with 250 milligrams intramuscular ketamine by paramedics. He had become increasingly paranoid after being off his aripiprazole for a few weeks, and his family had become afraid for his and their safety. Paramedics administered ketamine to control his combative agitation, per protocol. The patient's extreme neck and back extension rapidly resolved with the administration of midazolam. Further history and workup did not reveal another cause for opisthotonos.

conclusionThis is the first reported case to our knowledge of ketamine-associated opisthotonos in the emergency setting. Emergency care providers should be aware of this potential side effect.
