The predictive potential and relationship of peripheral non-enzymatic antioxidants with clinical symptoms in first-episode male adolescent-onset schizophrenia patients.
Article in Annals of general psychiatry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundOxidative stress is associated with the pathophysiology of schizophrenia. Peripheral non-enzymatic antioxidants can reflect the degree of oxidative stress and antioxidant levels, and can be used as markers of oxidative stress. However, the relationships between these markers and the clinical phenotypes of first -episode adolescent-onset schizophrenia (AOS) is unclear. This study aimed to elucidate the impact of peripheral non - enzymatic antioxidants on male AOS patients and their association with clinical symptoms.
methodsSerum albumin (ALB), total bilirubin (TBIL), and uric acid (UA) of 59 first-episode AOS patients and 55 healthy controls were measured respectively. Furthermore, schizophrenia-related clinical symptoms were evaluated using the five-factor model of the Positive and Negative Syndrome Scale (PANSS).
resultsIn Han Chinese first-episode male AOS patients, levels of TBIL and UA were significantly increased (p < 0.05), while ALB decreased (p < 0.01) compared with healthy controls. Furthermore, multivariate logistic regression showed that UA, ALB, and TBIL (all p < 0.01) were independently associated with AOS. Moreover, correlation analysis revealed that ALB was positively correlated with the PANSS total, cognitive and excited factor scores (all p < 0.05); TBIL was positively correlated with the excited factor score (p < 0.01); UA was positively correlated with the PANSS total, negative, cognitive and excited factor scores (all p < 0.05). In addition, Receiver operating characteristics assessment indicated that ALB and TBIL could effectively distinguish AOS patients from healthy controls.
conclusionsThis study confirms the association of peripheral non-enzymatic antioxidants (ALB, TBIL, and UA) with clinical manifestations and pathophysiology in schizophrenia. ALB and TBIL may serve as potential biomarkers for oxidative stress and symptom severity in AOS, particularly in males, providing insights for diagnostic and therapeutic strategies.
