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

Aberrant dopamine and glutamate signaling are implicated in the pathophysiology of schizophrenia. Existing treatments primarily target dopamine pathways underlying positive symptoms but have relatively little effect on cognitive and negative symptoms. Glutamatergic modulators may treat the latter symptom domains, and neuroimaging studies have the potential to identify therapeutic mechanisms. We conducted a systematic review to examine functional neuroimaging studies of glutamatergic modulators in psychosis and determine whether these agents alter brain activity, chemistry, or functional connectivity and whether such changes map onto clinical outcomes. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO: CRD42024549120), MEDLINE, Embase, and PsycInfo were searched from inception to June 2024 for studies administering pharmacologic glutamate modulators to individuals with psychosis, using functional neuroimaging (proton magnetic resonance spectroscopy [
