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

Deletions of the PAFAH1B1 gene (encoding LIS1) in 17p13.3 result in isolated lissencephaly sequence, and extended deletions including the YWHAE gene (encoding 14-3-3epsilon) cause Miller-Dieker syndrome. We identified seven unrelated individuals with submicroscopic duplication in 17p13.3 involving the PAFAH1B1 and/or YWHAE genes, and using a 'reverse genomics' approach, characterized the clinical consequences of these duplications. Increased PAFAH1B1 dosage causes mild brain structural abnormalities, moderate to severe developmental delay and failure to thrive. Duplication of YWHAE and surrounding genes increases the risk for macrosomia, mild developmental delay and pervasive developmental disorder, and results in shared facial dysmorphologies. Transgenic mice conditionally overexpressing LIS1 in the developing brain showed a decrease in brain size, an increase in apoptotic cells and a distorted cellular organization in the ventricular zone, including reduced cellular polarity but preserved cortical cell layer identity. Collectively, our results show that an increase in LIS1 expression in the developing brain results in brain abnormalities in mice and humans.
