Pro-cognitive effects of 5-HT4 receptor agonism in individuals with remitted depression.
Trial report in Psychological medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundCognitive impairment is a common and persistent feature of depression, yet it remains poorly understood and inadequately treated. Preclinical and human studies suggest that stimulating 5-HT
methodsFifty participants who were not currently depressed but had experienced at least two previous episodes of depression were randomized in a double-blind design either to prucalopride (2 mg daily, titrated from 1 mg) or to placebo for 7-10 days. Participants completed self-report questionnaires and a task battery at baseline and post-intervention assessing declarative memory, working memory, emotional processing, and executive function.
resultsCompared to placebo, prucalopride significantly improved word recall on an auditory verbal learning task and was associated with faster response times on a complex working memory task without loss of accuracy. It also improved the accurate recognition of rapidly presented facial expressions. Composite analysis of non-emotional tasks identified that the prucalopride group participants post-intervention were faster and more accurate than at baseline compared to those receiving placebo. Prucalopride had minimal effects on affective cognition, consistent with previous findings. Cognitive improvements were independent of baseline mood symptoms or self-reported cognitive difficulties.
