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

The illicit drug 3,4-methylenedioxymethamphetamine (MDMA) has recently shown promising efficacy as an adjunct to psychotherapy for posttraumatic stress disorder (PTSD), although the underlying mechanisms are poorly defined. In this review, we contextualize the emergence of MDMA-assisted psychotherapy (MDMA-AT) within 20th century psychiatry and trace its journey from assisting with military interrogation, through prohibition and to clinical use. We outline three core domains of MDMA's subjective effects-prosocial behaviour, reduced threat perception and euphoria-and explore how each may relate to its therapeutic efficacy and abuse liability. Drawing from clinical, behavioural, and pharmacological studies, we highlight the central role of 5-HT (serotonin) in mediating the effects of MDMA, while identifying key gaps in our understanding of its mechanism of action. We also assess how preclinical models capture therapeutic-relevant processes, discuss the limitations of existing data (including sex biases and an assumed role for therapeutic alliance) and suggest strategies to unravel the neurobiological basis of MDMA's therapeutic effects. Clarifying these mechanisms will be critical for optimizing future clinical protocols, mitigating risks and guiding the clinical development of safer, mechanistically informed MDMA-like therapeutic agents.
