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

Angelman syndrome (AS) and Prader-Willi syndrome (PWS) are neurodevelopmental disorders of genomic imprinting. AS results from loss of function of the ubiquitin protein ligase E3A (UBE3A) gene, whereas the genetic defect in PWS is unknown. Although induced pluripotent stem cells (iPSCs) provide invaluable models of human disease, nuclear reprogramming could limit the usefulness of iPSCs from patients who have AS and PWS should the genomic imprint marks be disturbed by the epigenetic reprogramming process. Our iPSCs derived from patients with AS and PWS show no evidence of DNA methylation imprint erasure at the cis-acting PSW imprinting center. Importantly, we find that, as in normal brain, imprinting of UBE3A is established during neuronal differentiation of AS iPSCs, with the paternal UBE3A allele repressed concomitant with up-regulation of the UBE3A antisense transcript. These iPSC models of genomic imprinting disorders will facilitate investigation of the AS and PWS disease processes and allow study of the developmental timing and mechanism of UBE3A repression in human neurons.
