Association between SMAD3 and SMAD7 gene polymorphisms and susceptibility to stress urinary incontinence in Chinese women.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThis study aimed to investigate the correlation between single nucleotide polymorphisms (SNPs) in SMAD3 and SMAD7 genes and the genetic risk of stress urinary incontinence (SUI) in Chinese women.
methodsA case-control study was conducted with 117 women diagnosed with SUI and 103 healthy controls. SNPs in SMAD3 (rs28683050, rs12901499) and SMAD7 (rs12953717, rs4939827) were analyzed using polymerase chain reaction-restricted fragment length polymorphism (PCR-RFLP). Allele and genotype frequencies were assessed using the SHEsis online platform. Epidemiological, clinical, and laboratory data were collected retrospectively. SUI patients underwent pelvic floor muscle training (PFMT), and treatment outcomes were evaluated after 3 months.
resultsThe G allele and GG genotype of rs12901499 in SMAD3 were significantly more common in the SUI case group (p_allele < 0.001, p_genotype = 0.002). Similarly, the T allele and TT genotype at rs12953717 in SMAD7 were more frequent in the SUI case group (p_allele = 0.002, p_genotype = 0.007). Multivariate logistic regression revealed that body mass index (BMI), family history, and the rs12901499 and rs12953717 polymorphisms were significant risk factors for SUI (P < 0.05). Furthermore, the TT genotype at rs12953717 was associated with poorer PFMT treatment outcomes.
conclusionOur findings suggest that the rs12901499 and rs12953717 polymorphisms are potential risk factors for SUI in women. Additionally, the rs12953717 polymorphism may influence the effectiveness of PFMT in SUI treatment.
