Ribosomal DNA gene copies are increased in blood and brain of Japanese schizophrenia patients.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Past evidence has indicated increased ribosomal DNA (rDNA) content in the blood of patients with schizophrenia (SCZ) among European populations. Here, for the first time, we investigated the rDNA copy number (rDNAcn) of SCZ in East Asian populations as well as in blood and brain tissues. In this study, we measured 18S/28S rDNAcn in the peripheral blood of live participants (81 patients with SCZ and 98 healthy controls) and the dorsolateral prefrontal cortices (DLPFCs) of postmortem individuals (10 patients with SCZ and 23 non-psychiatric controls) in the Japanese population. Patients with SCZ had significantly increased 18S/28S rDNAcn in the blood compared to controls (p < 0.05). 18S rDNAcn was significantly increased in the brain of patients with SCZ compared to controls (p < 0.05). In conclusion, regarding the increased rDNAcn in the blood of patients with SCZ that was previously reported in Europeans, we successfully replicated this by using a different, ethnically East Asian, cohort. Additionally, we provide the first evidence of increased rDNAcn in the brain of patients with SCZ. These findings may help to elucidate the molecular underpinnings of SCZ pathophysiology related to ribosomal DNA abnormalities.
