Association of PBRM1 rs2251219 with major depressive disorder and biochemical variables in a Taiwanese cohort.
Article in Journal of the Chinese Medical Association : JCMA, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundGenetic studies have identified more than 100 loci linked to major depressive disorder (MDD), underscoring its polygenic characteristics. Although the protein polybromo-1 ( PBRM1 ) rs2251219 polymorphism was reported to be associated with MDD, this has not been corroborated by additional studies. In the present study, the associations between PBRM1 rs2251219, MDD, and key biochemical variables were evaluated in a large Taiwanese cohort.
methodsData were collected from 117 679 individuals aged 30 to 90 years who were enrolled in the Taiwan Biobank. MDD diagnoses were based on self-reported data validated through national insurance claims records. Genotyping was conducted with an Axiom Genome-Wide Array, and associations with biochemical variables were analyzed through a general linear model adjusted for age and sex.
resultsA significant association was observed between PBRM1 rs2251219 and MDD risk ( p = 0.021 for genotype and p = 0.025 for allele). Individuals with the T allele had a higher MDD risk than C/C genotype carriers did. Biochemical differences were also observed, with T/T carriers with lower body mass index, platelet counts, albumin concentrations, and fasting glucose levels and higher red blood cell counts, hematocrit levels, and uric acid levels.
conclusionThe PBRM1 rs2251219 polymorphism was associated with both MDD and biochemical measurement variation. These findings support the effects of the PBRM1 rs2251219 polymorphism on blood protein levels and psychiatric traits.
