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

Two mutations in alpha-synuclein, the main constituent of Lewy bodies, have been identified in familial Parkinson's disease. We have stereotactically injected lentiviral vectors encoding wild-type and A30P mutant human alpha-synuclein in different brain regions (striatum, substantia nigra, amygdala) of mice. Overexpression of alpha-synuclein induced time-dependent neuropathological changes reminiscent of Lewy pathology: abnormal accumulation of alpha-synuclein in cell bodies and neurites, alpha-synuclein-positive neuritic varicosities and cytoplasmic inclusions that stained with ubiquitin antibodies and became larger and more frequent with time. After one year, alpha-synuclein- and ubiquitin-positive neurons displayed a degenerative morphology and a significant loss of alpha-synuclein-positive cells was observed. Similar findings were observed with both the wild-type and the A30P mutant form of alpha-synuclein and this in different brain regions. This indicates that overexpression of alpha-synuclein is sufficient to induce Lewy-like pathology and neurodegeneration and that this effect is not restricted to dopaminergic cells. Our data also demonstrate the use of lentiviral vectors to create animal models for neurodegenerative diseases.
