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

Cytosine DNA methylation is widespread in animal genomes and occurs predominantly at CG dinucleotides (mCG). While the roles of mCG, such as in genomic imprinting and genome stability, are well established, non-CG DNA methylation (mCH) remains poorly understood. In most vertebrate tissues, roughly 80% of CGs are methylated, whereas mCH levels are generally low, typically ranging from 1% to 3%. In vertebrates, mCH is most prevalent in neural tissue, oocytes and embryonic stem cells and has been linked to neurodevelopmental disorders. Moreover, mCH appears to have a conserved role in regulating vertebrate neural genomes, and recent studies suggest that it has functions in the embryogenesis of teleost fish. Overall, mCH represents an intriguing emerging aspect of gene regulation with potential implications for cellular identity, repeat silencing and neural function. In this Review, we provide a critical overview of the patterning, mechanisms and functional implications of mCH in animals.
