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

backgroundMDMA has been shown to induce feelings of sociability, a positive emotional bias and enhanced empathy. While previous research has used only visual emotional stimuli, communication entails more than that single dimension and it is known that auditory information is also crucial in this process. In addition, it is, however, unclear what the neurobiological mechanism underlying these MDMA effects on social behaviour is. Previously, studies have shown that MDMA-induced emotional excitability and positive mood are linked to the action on the serotonin (5-HT) 2A receptor.

aimThe present study aimed at investigating the effect of MDMA on processing of sounds (Processing of Affective Sounds Task (PAST)) and cognitive biases (Approach-Avoidance Task (AAT)) towards emotional and social stimuli and the role of 5-HT

methodsTwenty healthy recreational users entered a 2 × 2, placebo-controlled, within-subject study with ketanserin (40 mg) as pre-treatment and MDMA (75 mg) as treatment. Behavioural (PAST, AAT) measures were conducted 90 min after treatment with MDMA, respectively, 120 min after ketanserin. Self-report mood measures and oxytocin concentrations were taken at baseline and before and after behavioural tests.

resultsFindings showed that MDMA reduced arousal elicited by negative sounds. This effect was counteracted by ketanserin pre-treatment, indicating involvement of the 5-HT

conclusionIt is suggested that this decrease in arousal to negative stimuli reflects potentially a lowering of defences, a process that might play a role in the therapeutic process.
