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

Parkinson's disease (PD) has been historically defined as a disease of striatal dopamine deficiency secondary to degeneration of dopaminergic neurons in the substantia nigra pars compacta, related to the presence of Lewy bodies and Lewy neurites. Since the discovery of pathogenic variants in the gene encoding α-synuclein, as well as the finding that α-synuclein is a major constituent of Lewy pathology, PD is considered as a prototypical synucleinopathy. However, neuropathological studies consistently show that most people with PD display copathologies, many of which are linked to specific clinical features and outcomes. In this review, we summarize the spectrum and frequency of these co- and multi-pathologies in idiopathic and genetic PD and their impact on disease initiation and progression. Additionally, we also discuss how this multi-pathological landscape may impact biomarker research and the implementation of emerging disease-modifying therapies. © 2026 The Author(s).
