Brain-derived neurotrophic factor (BDNF) changes in rodent models of schizophrenia induced by ketamine: a systematic review.
Synthesis in Naunyn-Schmiedeberg's archives of pharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Schizophrenia is a severe neuropsychiatric disorder ranking among the top ten global disability causes. In rodents, sub-chronic or chronic ketamine treatment is used for the induction of schizophrenia. Ketamine affects the function of brain-derived neurotrophic factor (BDNF), the most important neurotrophin involved in the pathophysiology of different neuropsychiatric disorders. The present systematic review aimed to investigate BDNF changes in rodent studies used ketamine-induced schizophrenia. PubMed electronic database was searched and 44 articles were found. After removal of unrelated articles, 17 articles were selected. The results showed a wide range of inconsistent changes in BDNF levels. We found that sub-chronic and chronic ketamine treatment in rats decreased BDNF or had no effect. Sub-chronic and chronic ketamine treatment in mice only decreased BDNF. However, increased BDNF was commonly observed following acute ketamine treatment. These results showed the possible role of species and the duration of treatment. Also, sex can also be involved in BDNF changes because one study showed inconsistent BDNF changes in male and female rats. In conclusion, we found that ketamine's effects may depend on factors such as duration of administration, sex, and species. Therefore, the wide range of BDNF changes may be related to high variability in methods. Because of this variability, there is currently no standardized method for using ketamine as a rodent model for schizophrenia. Further research is needed to establish a standardized pharmacological model of schizophrenia using ketamine treatment.
