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

In this study the authors investigated whether dysregulation of the fragile X mental retardation protein and mammalian target of rapamycin signaling cascade can have a role in the pathogenesis of encephalopathy of prematurity following perinatal hypoxia-ischemia. The authors examined the brain tissue of newborns with encephalopathy and compared it to age-matched controls with normal brain development and adults. In normal controls, the fragile X mental retardation protein expression in cortical gray matter spiked 4-fold during 36-39 gestational weeks compared to the adult, with a concomitant suppression of p70S6K and S6. In encephalopathy cases, the developmental spike of fragile X mental retardation protein was not observed, and fragile X mental retardation protein levels remained significantly lower than in normal controls. Importantly, this fragile X mental retardation protein downregulation was followed by a significant overexpression of p70S6K and S6. These novel findings thus suggest that premature hypoxic-ischemic brain injury can affect the fragile X mental retardation protein/mammalian target of rapamycin pathway, as otherwise observed in inherited syndromes of cognitive disability and autism spectrum disorders.
