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

Imprinted genes are monoallelically expressed according to the parent of origin and are critical for proper placental and embryonic development. Disruption of methylation patterns at imprinted loci resulting in loss of imprinting (LOI) may lead to serious imprinting disorders (e.g., Beckwith-Wiedemann syndrome) and is described in some cancers (e.g., Wilms' tumor). As most research has focused on children with cancer or other abnormal phenotypes, the imprinting status in healthy infants at birth has not been characterized. We examined the prevalence of H19 and IGF2 LOI at birth by allele-specific expression assays analysis on 114 human individuals. Overall expression and methylation analyses were performed on a subset of samples. We found that LOI of H19 was observed for 4% of individuals in cord blood and 3.3% in placenta, and for IGF2 of 22% of individuals in the cord blood and 0% in placenta. Interestingly, LOI status did not correspond to aberrant methylation levels of the imprinted DMRs or with changes in overall gene expression for the majority of individuals. Our observations suggest that LOI is present in phenotypically healthy infants. Determining a "normal" human epigenotype range is important for discovering factors required to maintain a healthy pregnancy and embryonic development.
