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

The aim of the present study was to examine the whole‑genome DNA methylation status of thymomas and identify differences in thymoma DNA methylation profiles. DNA methylation profiles of tissues (n=12) were studied using the Infinium MethylationEPIC BeadChip microarray (850K) and analyzed in relation to gene expression data. Functional annotation analysis of DNA methylation between the different groups was performed using the online tool GeneCodis3. In order to assess the diagnostic value of candidate DNA methylation markers, receiver operation characteristic (ROC) analysis was performed using the pROC package. A total of 10,014 CpGs were found to be differentially methylated (Δβ>0.2) between two thymoma types (type A and B). Combination analysis showed that 36 genes had differentially methylated CpG sites in their promoter region. 'Pathways in cancer', 'focal adhesion' and 'regulation of actin cytoskeleton' were the most enriched KEGG pathways of differentially methylated genes between tumor and controls. Among the 29 genes that were hypomethylated with a high expression, zinc finger protein 396 and Fraser extracellular matrix complex subunit 1 had the largest area under the curve. The present results may provide useful insights into the tumorigenesis of thymomas and a strong basis for future research on the molecular subtyping of epigenetic regulation in thymomas.
