NGF-β and BDNF levels are altered in male patients with chronic schizophrenia: effects on clinical symptoms.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundSchizophrenia, a severe mental disorder with complex pathophysiology, involves neurotrophic factors, which play crucial roles in neurodevelopment and neuroplasticity. This study investigated NGF-β and BDNF levels in chronic schizophrenia and their association with clinical symptoms, cognitive function, and 1,25(OH)₂D levels.
methodsIn this cross-sectional study, 72 male patients with chronic schizophrenia and 70 matched healthy controls were enrolled. Psychopathological symptoms were assessed using the Positive and Negative Syndrome Scale (PANSS), and cognitive function was evaluated using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The serum levels of NGF-β, BDNF, and 1,25(OH)₂D were measured.
resultsSerum levels of NGF-β (F = 35.239, P < 0.001) and BDNF (F = 12.669, P < 0.001) were significantly decreased in patients with chronic schizophrenia compared to healthy controls. NGF-β levels were negatively correlated with PANSS negative symptoms (beta = -0.205, t = -2.098, P = 0.040) and positively correlated with 1,25(OH)₂D levels (r = 0.324, P = 0.006). Decreased serum BDNF concentrations were negatively correlated with language deficits (beta = -0.301, t = -2.762, P = 0.007). Significant associations were observed between chronic schizophrenia and reduced levels of NGF-β (B = 1.040, P < 0.001, RR = 2.829, 95% CI: 2.101-3.811) and BDNF (B = 0.526, P = 0.001, RR = 1.692, 95% CI: 1.241-2.306).
conclusionsOur findings indicated that NGF-β and BDNF levels were altered in chronic schizophrenia and were associated with clinical symptoms and vitamin D metabolism. These results provided new insight into the etiology of schizophrenia.
