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

Oxidative stress (OS) is crucial in schizophrenia (SCZ) pathology. Ferroptosis, a recently discovered cell death pathway linked to OS, might contribute to the development of SCZ. This study investigated the association between ferroptosis markers and cognitive impairments in chronic SCZ patients. A retrospective analysis was conducted on 204 chronic SCZ patients with cognitive deficits and 216 healthy controls (HC) matched for relevant characteristics. Plasma levels of ferroptosis and OS markers, including iron, ferritin (FE), transferrin (TF), glutathione peroxidase 4 (GPX4), long-chain acyl-CoA synthetase 4 (ACSL4), glutathione (GSH), sirtuin 1 (SIRT1), nuclear factor erythroid 2-related factor 2 (Nrf2), malondialdehyde (MDA), and superoxide dismutase (SOD) were measured. Standardized assessments like the positive and negative syndrome scale (PANSS), and Montreal Cognitive Assessment (MoCA) were used to evaluate psychiatric symptoms, and cognitive function. SCZ patients showed significant differences in markers compared to the HC group (P < 0.01). Multiple linear regression analysis revealed that decreased GSH and iron levels, along with elevated SOD levels, were significantly associated with the overall severity of psychiatric symptoms. Additionally, reduced GPX4 levels and increased ACSL4 and FE levels were significantly linked to negative symptoms and cognitive impairments. Notably, GPX4 emerged as a key predictor for cognitive function in abstraction and language domains. Our study revealed alterations in the altered plasma levels of GPX4, GSH, iron, ACSL4, FE, and SOD in chronic SCZ patients, which might indicate a close association between biomarkers of ferroptosis and OS and the psychiatric symptoms and cognitive deficits observed in these individuals.
