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

Neonatal hypoxic-ischemic (HI) encephalopathy can lead to severe brain damage and is a common cause of neurological handicaps in adulthood. To elucidate the molecular events occurring in cerebral cortices of mature rats (8 weeks old) after neonatal HI brain insult, we performed comprehensive gene expression and gene network analyses using a DNA microarray system (Agilent 4x44K). A rat model of neonatal HI encephalopathy (Rice model) was obtained by unilateral ligation of the common carotid artery of 7-day-old rats with hypoxia (exposure to 8 % oxygen). Due to the HI insult-related breakdown of the ipsilateral hemisphere in the brain, RNAs were prepared from the contralateral cerebral cortices of 8-week-old rats and analyzed by DNA microarray. Biofunctional analysis of differentially regulated genes revealed that many upregulated genes were related to cell death signaling, such as the arachidonic acid cascade. In contrast, many downregulated genes were related to gene expression, reflecting progressive damage by the HI insult, even within the contralateral cerebral hemisphere.
