Characterization of Small Genetic Variants in Breast Cancer Cell Line Under Tamoxifen Therapy.
Article in Galen medical journal, 2023. 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
backgroundTamoxifen (TAM) is an effective hormone therapy in order to reduce the risk of cancer recurrence. According to the available findings, TAM contributes to the alterations of genetic variants background and may have role in the effectiveness of treatments via alteration of the genetic variants. The effects of TAM on genomic features were investigated in current study through discovering genetic variants and finding the answer of the following question: "Is there any association between the alterations of genetic variants under TAM consumption and an effective treatment process?" MATERIALS AND
methodsWhole-transcriptome (RNA-seq) dataset of four investigations including 10 TAM-treated samples and 9 untreated samples as the control groups were derived from European Bioinformatics Institute (EBI). Using the process of variants calling, the differential genetic variants between and gene ontology enrichment analysis were detected through CLC Genomics Workbench (12).
resultsIn current study, almost 5.8 million genetic variants were reported. The outcomes of chi-square test showed that distributions of genetic variants between control and treated samples were significant (P0.05). The genetic variants comparison between the control and TAM-treated samples indicated that there were 67 differential genetic variants. Gene ontology enrichment analysis indicated that differential genetic variants were associated with several tumor suppressors and oncogenes such as IL6ST, GEN1, FNTA. HSPA5, NSMCE2, and DDX11.
conclusionMost of the candidate genes with differential genetic variants had dual roles as oncogenes or tumor suppressors. Therefore, it can be claimed that TAM has no significant role in an effective treatment through alteration of the genetic variants. In other words, it cannot be concluded that the TAM therapy-resulted alterations of genetic variants have positive or negative roles in the treatment process.
