1 · What the graph read from it

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.

2 · The registry

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

There are several risk factors related to Breast Cancer (BC) risks and response to chemotherapy with SERMs. Recently some single nucleotide polymorphisms (SNPs) on ESR1 gene have been associated to this disease. However, data are still inconclusive. The present study aimed to investigate the association of SNPs c454-397T>C (also called PvuII) and c454-351A>G (so called XbaI) to incidence of sporadic BC; ERα expression in BC; tamoxifen hormonetherapy (HT-TMX) responsiveness. To do so, a cohort of BC patients was analyzed through retrospective data collection, immunohistochemistry to ERα protein, and genotyping for PvuII and XbaI SNPs by PCR-RFLP, confirmed by sequencing. Significant difference in PvuII alleles frequencies were found BC patients when compared to control samples. Patients with P allele have a 5.14-fold increased BC risk. We found higher P and X alleles frequencies in ERα positive BC and the pp and xx genotypes were observed exclusively in patients with HT-TMX-responsive BC. Taken together, data indicates that P allele as a novel sporadic BC biomarker whereas p and x alleles enhanced chemotherapy responsiveness.
