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 use of assisted reproductive technologies (ART) has become increasingly common worldwide and is now responsible for 2-3% of children born in developed countries. Multiple reports have suggested that ART-conceived children are more likely to develop rare epigenetic disorders such as Beckwith-Wiedemann Syndrome or Angelman Syndrome, both of which involve dysregulation of imprinted genes. Anecdotal reports suggest that animals produced with ART that manifest apparent epigenetic defects typically do not transmit these epimutations to subsequent generations when allowed to breed naturally, but this hypothesis has not been directly studied. We analyzed allele-specific DNA methylation and expression at three imprinted genes, H19, Snrpn, and Peg3, in somatic cells from adult mice generated with the use of intracytoplasmic sperm injection (ICSI), a type of ART. Epimutations were detected in most of the ICSI-derived mice, but not in somatic cells of their offspring produced by natural mating. We examined germ cells from the ICSI mice that exhibited epimutations in their somatic cells and confirmed normal epigenetic reprogramming of the three imprinted genes analyzed. Collectively, these results confirm that ART procedures can lead to the formation of primary epimutations, but while such epimutations are likely to be maintained indefinitely in somatic cells of the ART-derived individuals, they are normally corrected in the germ line by epigenetic reprogramming and thus, not propagated to subsequent generations.
