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
introductionSchizophrenia is a heterogeneous chronic brain disorder driven by multiple pathophysiological processes. While dopaminergic theories dominate current therapies, emerging evidence highlights glutamatergic dysregulation, particularly N-methyl-D-aspartate receptor (NMDAR) hypofunction, as a key mechanism alongside dopaminergic, serotonergic, and neurodevelopmental pathways. This article synthesizes mechanistic insights, focusing on neurotransmitter disruptions, oxidative stress, neuroinflammation, and Wnt signaling, to elucidate the clinical diversity of schizophrenia and identify biomarkers for precise diagnostics and therapeutics.
methodsA comprehensive literature search was conducted using Web of Science, Scopus, Google Scholar, and PubMed, with keywords including "schizophrenia," "psychosis," "pathophysiology," "mechanism," and "biomarker." Studies were selected to explore NMDAR hypofunction, glutamatergic dysregulation, and associated signaling pathways, integrating preclinical and human data to map circuit-based interactions and biomarker profiles.
resultsWe present a novel circuit-based model of schizophrenia pathophysiology, centered on NMDAR hypofunction and glutamatergic dysregulation, integrating dopaminergic, GABAergic, and inflammatory pathways. Key biomarkers, including inflammatory (e.g., high-sensitivity Creactive protein [hs-CRP], interleukin-6 [IL-6]), neurochemical (e.g., brain-derived neurotrophic factor [BDNF]), and functional (e.g., mismatch negativity [MMN]), are categorized by symptomatic domains and clinical stages, providing diagnostic and prognostic insights. DISCUSSIONS: The findings underscore NMDAR hypofunction's role in driving schizophrenia's symptomatic spectrum, though its interplay with other pathways highlights the disorder's complexity. Neuronal loss, although not universal, is context-specific (e.g., hippocampal interneurons), complementing functional biomarkers such as MMN. Limitations include the need for robust human validation of biomarkers and broader exploration of non-glutamatergic mechanisms.
conclusionConsidering the multifaceted nature of the disorder, our emphasis on the NMDAR hypofunction model can help explain many of the synergies involved among the seemingly independent dysregulated events.
