The impact of SLCO1B1 polymorphisms on homocysteine concentrations: evidence for a stronger association in men.

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
Background: Homocysteine (Hcy) is a risk factor for stroke. In this study, we investigated the relationship between gene polymorphisms, particularly SLCO1B1 and homocysteine (Hcy) concentrations in ischemic stroke patients, with a focus on identifying potential risk factors for elevated Hcy levels. Methods: A total of 177 ischemic stroke patients, including 99 with single nucleotide polymorphisms (SNPs), underwent pharmacogenomics (PGx) sequencing tests, from September 2022 to November 2023 at the hospital. Logistic regression analysis was used to analyze the relationship between clinical characteristics, SNPs, and Hcy concentrations. In the sub-study, 207 ischemic stroke and 244 non-stroke patients underwent SLCO1B1c.521T>C polymorphism to further demonstrate the role of SLCO1B1c.521T>C polymorphism and homocysteine. Results: Higher Hcy concentrations were observed in men compared to women. Univariate logistic analysis identified gender, GGT concentrations, B12 concentrations, folic acid concentrations, and SLCO1B1 c.521 CC+CT polymorphism as risk factors for elevated Hcy. Multivariate logistic analysis confirmed that B12 concentrations, folic acid concentrations, and SLCO1B1 CT + CC polymorphism were significant dependent risk factors. In the sub-study, SLCO1B1 CT + CC polymorphism and the male sex were identified as risk factors for Hcy, with the effect of SLCO1B1 polymorphism being more pronounced in men. Conclusion: Folic acid and vitamin B12 reduce Hcy concentrations, while the SLCO1B1 CT and CC polymorphisms are associated with higher Hcy levels. The impact of SLCO1B1 gene polymorphism on Hcy is notably stronger in the male population, suggesting that genetic factors play a significant role in determining Hcy levels.
