Interplay between NOD1 polymorphisms and gene expression in the pathogenesis of gallstone disease.
Article in Molecular biology reports, 2026. 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
backgroundGallstone disease (GSD) is a multifactorial disorder with both genetic and inflammatory influences. Nucleotide-binding oligomerization domain containing protein 1 (NOD1) has an important role in innate immunity and in regulation of gut microbiota and its genetic relationship to GSD is unknown.
aimTo explore the association of NOD1 gene polymorphism (rs5743336 and rs6958571) and gene expression with gallstone disease.
methodsA case-control study was carried out with ultrasound diagnosed gallstone patient and age and sex matched controls. Genotyping of rs5743336 and rs6958571 was done by PCR-RFLP. NOD1 mRNA expression was measured by qRT-PCR. Statistical analysis comprised comparisons of genotype and allele frequencies and logistic regression under various genetic models was performed.
resultsThe rs5743336 (GG) genotype was significantly less common in cases than in controls, suggesting a protective effect against GSD (p < 0.05). No significant association was found for rs6958571. In addition, NOD1 expression levels were significantly lower in GSD cases than controls (fold change = 0.415443; p-value = 0.038407) and impaired microbial sensitivity may contribute to gallstone pathogenesis.
conclusionThis is the first study to find an association between NOD1 genetic variation and gallstone disease. The GG genotype of rs5743336 is protective, and decreased NOD1 expression could be a factor in the development of disease.
