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

Status epilepticus in the immature brain induces neuronal injury in the hippocampal formation, but the mode and mechanism of death are poorly understood. Our laboratory has recently investigated the role of caspase-3, -8, and -9 in neuronal injury, using a lithium-pilocarpine model of status epilepticus in 2-week-old rat pups. Our results showed that dying neurons in the dentate gyrus and CA1-subiculum area do not share the same mechanism of death. In CA1-subiculum, caspase-8 upregulation preceded caspase-3 activation in morphologically necrotic neurons. The pan-caspase inhibitor Q-VD-OPH reduced CA1 damage, showing that caspases contribute to status epilepticus-induced necrosis. In the dentate gyrus, dying neurons were caspase-9 and -3 immunoreactive and morphologically apoptotic. It is not clear why the same seizures cause different types of cell death in neurons that are connected in series along the same hippocampal circuit, but the apoptotic dentate neurons express doublecortin, and do not express calbindin-D28k, suggesting that their immaturity may be a factor in producing an apoptotic mode of death.
