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

An important link between neuroactive steroids and neurodegenerative disorders has recently been suggested. Indeed, in several neurodegenerative experimental models the levels of neuroactive steroids are affected and their administration exerts neuroprotective effects. However, scarce information has so far been obtained on the neuroactive steroid levels present in Parkinson's disease. To this aim, using an experimental model of loss of nigrostriatal dopaminergic neurons obtained by stereotaxic injection of the neurotoxin 6-hydroxydopamine (6-OHDA), we evaluated by liquid chromatography tandem mass spectrometry the levels of several neuroactive steroids in the striatum and cerebral cortex of 6-OHDA-lesioned male rats. Among the neuroactive steroid levels assessed (i.e., pregnenolone, progesterone, dihydroprogesterone, tetrahydroprogesterone, isopregnanolone, testosterone, dihydrotestosterone, 3α-diol, dehydroepiandrosterone, 17α-estradiol, and 17β-estradiol), we observed a significant decrease of pregnenolone in the striatum. A similar effect was also observed on the levels of dihydroprogesterone present in this cerebral area and also in the cerebral cortex. Interestingly, an increase of isopregnanolone also occurred in the striatum and in the cerebral cortex. Altogether, these results suggesting that progesterone metabolism is affected in an experimental model of Parkinson's disease further highlight the link between neuroactive steroids and the neurodegenerative diseases.
