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

backgroundThe option of endocrine therapy in breast cancer remains conventionally promising.

objectiveWe aimed to investigate how accurately the pattern of hypermethylation at estrogen receptor (ESR) and progesterone receptor (PgR) genes may associate with relative expression and protein status of ER, PR and the combinative phenotype of ER/PR.

methodsIn this consecutive case-series, we enrolled 139 primary diagnosed breast cancer. Methylation specific PCR was used to assess the methylation status (individual test). Tumor mRNA expression levels were evaluated using real-time RT-PCR. Immunohistochemistry data was used to present hormonal receptor status of a tumor (as test reference).

resultsMethylation at ESR1 was comparably frequent in ER-breast tumors (83.0%, P< 0.001; sensitivity = 83.0%, specificity = 65.2% and diagnostic odds ratio, DOR = 12.0) and strongly correlated with ER-/PR- conditions (Cramer's V= 0.44, P< 0.001). Methylated PgRb promoter frequently was observed in tumors recognised as ER- or negative ER/PR (77.1%, P< 0.01). Assessment of DNA methylation of ESR1 harbouring methylation at PgRb was a case significantly suggested to be able to detect the lack of ER/PR expressions (55.6%, P< 0.01; sensitivity = 80.6%, specificity = 68.7% and DOR = 8.7). However, methylated PgRb was quite acceptable determinant to contribute with methylated ESR1 to rank tumors as ER-/PR- (64.4%, P< 0.01; sensitivity = 78.0%, specificity = 62.5% and DOR = 6.0).

conclusionsDespite the methylation status of ESR1 showed preponderant contribution to tumoral phenotypes of ER- and ER-/PR-, the hypermethylation of PgRb seem another epigenetic signalling variable actively associate with methylated ESR1 to show lack of ER+/PR+ tumors in breast cancer.
