Epistatic interaction of Arg72Pro TP53 and -710 C/T VEGFR1 polymorphisms in breast cancer: predisposition and survival.
Article in Molecular and cellular biochemistry, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
The tumour-suppressor gene TP53 has been associated with the angiogenic pathway by a TP53 response element sequence of the VEGFR1 promoter. Within that sequence, the polymorphism -710 C/T VEGFR1, which confers variable transcriptional activation by TP53, has been identified. Our group found an association between this polymorphism and breast cancer (BC) risk. We decided to investigate a possible epistatic interaction between this polymorphism and others located at gene TP53. We chose four polymorphisms (Ex4 + 119G > C, IVS4-91A > G, IVS6 + 62A > G and IVS7 + 92T > G) to analyse out of a total of 461 controls and 453 BC patients in a Spanish population. The two-locus combined analysis of TP53 and -710 C/T VEGFR1 polymorphisms was performed with the multifactor dimension reduction approach. Kaplan-Meier disease-free survival curves were calculated using the SPSS package. Carriers of at least one Pro allele of the Ex4 + 119G > C TP53 polymorphism presented a significant BC risk [OR = 1.34, (95 % CI 1.03-1.75), p value = 0.029]. The epistatic gene-gene analysis showed that the best two-locus model was the combination between Ex4 + 119G > C TP53 and -710 C/T VEGFR1 showing OR of 1.44 (95 % CI 1.10-1.88, p value = 0.0083). Moreover, the Pro/Pro genotypes of Ex4 + 119G > C were associated with poor disease-free survival (p value = 0.013). We conclude that the Ex4 + 119G > C TP53 polymorphism is an independent, low penetrance marker of BC risk in this population. In addition, our findings suggest that the combination of Ex4 + 119G > C TP53 and -710 C/T VEGFR1 genotypes confers a higher risk to develop BC. Also, a possible association of the Ex4 + 119G > C TP53 genotype with decreased disease-free survival in these patients is proposed.
