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

Based on post-mortem studies, a long-standing hypothesis on the biological bases of specific reading disabilities (RD) has been that alterations in neuronal migration alter language neural circuits. However, there are questions concerning the original studies (small sample size, comorbidities). Further, this idea has not been strongly supported by current genetic studies. In this study, we test altered neural cell phenotypes using cells derived from two pairs of siblings strongly discordant for reading-probands with severe RD and their strong-reader siblings. We observed significant differences in neurosphere outgrowth between the neural precursor cells (NPCs) from the probands compared to their strong-reader siblings. Transcriptome analyses of adherent NPCs and neurons derived from the NPCs identified genes differentially expressed between the probands and siblings, including genes previously identified in neurodevelopmental disorders. Of note was the overexpression of the hormone IGF1 and the transcription factor OTX2, responsible for the opening and closing of critical windows in development and predicted to be involved in critical windows for language acquisition. Our results support altered transcriptome and cellular phenotypes in RD neural cells and suggest possible molecular mechanisms underlying the changes.
