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

There is emerging evidence from animal studies for a neuroprotective role of sex steroids in neurodegenerative diseases, but studies in human brain are lacking. We have carried out an extensive study of the neurosteroid biosynthetic pathways in substantia nigra (SN), caudate nucleus (CN) and putamen (PU) of 7 Parkinson's disease (PD) patients and 7 matched controls. The mRNA levels of 37 genes including neurosteroid biosynthetic enzymes, hormone receptors and the neurosteroid-modulated gamma-amino-butyric acid -A (GABA-A) receptor subunits were analyzed by quantitative PCR (qPCR). In the SN, we found downregulation of 5alpha-reductase type 1 (5alpha-R1), sulfotransferase 2B1 (SULT2B1) and some GABA-A receptor subunits (alpha4, beta1) while in the CN, upregulation of 3alpha-hydroxysteroid dehydrogenase type 3 (3alpha-HSD3) and alpha4 GABA-A receptor subunit (22-fold) was observed. No significant differences were found in the PU. These data imply an involvement of pregnane steroids and changes in GABAergic neurotransmission in the neurodegenerative process and suggest that neurosteroids may deserve further investigation as potential therapeutic agents in PD.
