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

Psychedelic experiences involving extreme feelings of horror, helplessness, and perceived threats can be traumatizing. Traumatic psychedelic experiences are a rare, extreme, and largely preventable form of challenging experience which can arise due to frightening psychedelic drug effects, unsafe settings, and emergence of pre-existing trauma. Some people recover quickly, but others develop prolonged anxiety, sleep disturbances, derealization, or other potentially trauma-related symptoms. This chapter discusses the causes, phenomenology, and potential outcomes of traumatic psychedelic experiences, as well as how to prevent them and minimize their negative impact.
