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

Cognitive deficits in schizophrenia are a major predictor of patient functional outcome, and current treatments have limited efficacy in targeting this symptom domain. Glutamatergic dysfunction is hypothesized to contribute to cognitive impairments, and administration of N-methyl-d-aspartate (NMDA) receptor antagonists to both healthy humans and animals causes behavioral and cognitive deficits similar to those observed in patients with schizophrenia. In particular, hypofunction of NMDA receptors on GABAergic interneurons in the medial prefrontal cortex (mPFC) leads to excessive pyramidal cell activity and is a hypothesized mechanism underlying these deficits. As such, therapeutic modulation of glutamatergic and GABAergic release in PFC-associated circuits may correct cognitive impairments in schizophrenia. Metabotropic glutamate (mGlu) receptors have emerged as a promising strategy to target this symptom domain due to their widespread expression in relevant brain regions and their implications within the glutamate system. Group III mGlu receptors (mGlu
