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 is a rare neurodevelopmental disorder caused by the loss of function of the maternally inherited UBE3A gene within the chr15q11-q13 region. This gene is subjected to a tissue-specific form of genomic imprinting leading to the silencing of the paternal allele in neurons. Angelman syndrome can result from various (epi)genetic mechanisms, with paternal uniparental disomy of chromosome 15 (patUPD15) being one of the rarest and least studied due to the absence of suitable models. To address this gap, we generated three independent induced pluripotent stem cell (iPSC) lines from individuals with Angelman syndrome caused by patUPD15, alongside genetically matched unaffected familial controls. Peripheral blood mononuclear cells (PBMCs) were reprogrammed into iPSCs using a non-integrative Sendai virus-based approach expressing the Yamanaka factors. All iPSC lines underwent rigorous quality control, confirming stem cell identity, trilineage differentiation potential, and genetic and epigenetic integrity. This newly established iPSC toolkit provides a powerful platform to investigate the molecular underpinnings of Angelman syndrome caused by patUPD15, paving the way for future translational research and therapeutic development tailored for this understudied form of the disorder.
