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

Since the discovery of oxidative demethylation of methylcytosine (mC) by Tet enzymes, an analytical method has been urgently needed that would enable the identification of mC and hydroxymethylcytosine (hmC) at the single base resolution level, because their roles in gene regulation are quite different from each other. However, the bisulfite sequencing method, the gold standard for DNA methylation analysis at present, does not distinguish them. Recently reported alternative methods, such as oxBS-seq and TAB-seq, are not even capable of determining mC and hmC simultaneously. Here, we report a novel method for the direct identification of mC, hmC and unmodified cytosine (C) at a single base resolution. We named this method the Enzyme-assisted Identification of Genome Modification Assay (EnIGMA), and it was demonstrated to indeed have a highly efficient and reliable analytic capacity for distinguishing them. We also successfully applied this novel method to the analysis of the maintenance of the DNA methylation status of imprinted H19-DMR. Importantly, hydroxymethylation plays an ambivalent role in the maintenance of the genome imprinting memory in parental genomes essential for normal development, shedding new light on the epigenetic regulation in ES cells.
