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

introductionIn this study, the global DNA methylation, histone acetylation and methylation levels of cumulus cells (CCs) in infertile polycystic ovary syndrome (PCOS) patients and the correlation of these epigenetic modifications with the expression of the ovarian aromatase gene (as an important marker in the etiology of PCOS) were investigated. MATERIAL AND

methodsA cross-sectional study was conducted on 24 patients (12 PCOS patients and 12 healthy women), who underwent ovarian stimulation. Nucleosome ELISA was performed, in order to identify the global occupancy level of Mecp2 (as a marker of DNA methylation) and H3K9me2/H3K9ac as histone modification markers in chromatin fractions obtained from CCs. The

resultsThe data demonstrate a significant increase in global occupancy levels of MeCP2 and H3K9ac markers and a decrease of H3K9me2 to chromatin in CCs of PCOS patients vs. control group. Furthermore,

conclusionsAromatase expression can be affected by epigenetic modifications and differential ERβ binding to the proximal
