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

backgroundSeveral lines of evidence support the hypothesis of brain-first and body-first Parkinson's disease (PD) subtypes, characterized by distinct origins of α-synuclein pathology. However, data on premotor non-motor burden and motor progression in these subtypes remain inconsistent.

objectiveTo analyze the natural history of body-first versus brain-first PD subtypes.

methodsData from 400 PD patients enrolled at a single Italian center were analyzed. All patients underwent a standardized retrospective baseline assessment of premotor and motor symptoms at onset and were prospectively followed. Premotor REM sleep behavior disorder (RBD), considered a prodromal phenotype of the body-first subtype, was used to divide patients into two groups: 81 patients with probable premotor RBD (PD

resultsAt motor onset, PD

conclusionsOur results align with the hypothesis of brain-first and body-first PD subtypes, providing novel insights into their different premotor non-motor burden and motor progression trajectories.
