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
objectiveSingle nucleotide polymorphisms (SNPs) are linked to carcinogenesis. Pathogenic variants in the CDH1 gene are associated with gastric cancer. This study examines the genotype and allele frequencies of three SNPs (rs16260, rs13689, and rs9929218) in the CDH1 gene and their relationship with gastric cancer risk. MATERIALS AND
methodsThe study involved 105 gastric cancer patients with pathology results and 105 healthy controls. Clinical, histopathological, and demographic data were collected and compared between the two groups.
resultsNo significant differences were found for rs16260 (- 160 C > A) and rs9929218 (G > A) between patients and controls (p > 0.05). For rs13689 (T > C), the T allele frequency was 90% in patients versus 69% in controls, while the C allele frequency was 10% in patients versus 31% in controls. A significant difference was observed for this SNP, with a higher T allele frequency in patients (OR = 4.03 CI95% 2.4-6.7, p < 0.0001) compared with controls, suggesting a fourfold increased risk of gastric cancer. Genotype frequencies were 80% wild-type (TT) and 20% heterozygous-type (TC) in patients, and 58% TT, 22% TC, and 20% mutant-type (CC) in controls (p < 0.0001). The frequencies of non-C allele carriers (TT) were present in 80% of patients versus 58.1% of controls (OR = 2.88 CI95% 1.56-5.34, p = 0.0006).
conclusionThis study is the first to link the rs13689 SNP's T allele and TT genotype with increased gastric cancer risk. Our results suggest that the rs13689 T allele may contribute significantly to disease susceptibility, while the rs16260 CC genotype and rs9929218 GG genotype may influence risk in smokers.
