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 adult brain invariably causes an increase in hippocampal neurogenesis and the appearance of ectopic cells and this has been implicated as a causal factor in epileptogenesis. The effect of status epilepticus on neurogenesis in the developing brain is less well characterized and models of early-life seizures typically do not reproduce the hippocampal damage common to human mesial temporal sclerosis. We recently reported that evoking status epilepticus by intra-amygdala microinjection of kainic acid in post-natal (P) day 10 rats caused substantial acute neuronal death within the ipsilateral hippocampus and rats later developed unilateral hippocampal sclerosis and spontaneous recurrent seizures. Here, we examined the expression of a selection of genes associated with neurogenesis and assessed neurogenic function in this model. Protein levels of several markers of neurogenesis including polysialic acid neural cell adhesion molecule, neuroD and doublecortin were reduced in the hippocampus three days after status epilepticus in P10 rats. In contrast, protein levels of neurogenesis markers were similar to control in rats at P55. Pulse-chase experiments using thymidine analogues suggested there was a reduction in new neurons at 72 h after status epilepticus in P10 rats, whereas numbers of new neurons labelled in epileptic rats at P55 with hippocampal sclerosis were similar to controls. The present study suggests that status epilepticus in the immature brain suppresses neurogenesis but the neurogenic potential is retained in animals that later develop hippocampal sclerosis.
