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

BackgroundCerebrospinal fluid (CSF) α-synuclein seed amplification assay (αS-SAA) is a recognized biomarker of synucleinopathy. In Parkinson's disease (PD), its potential for predicting clinical outcome needs to be further assessed.ObjectiveTo evaluate the associations between clinical outcome and αS-SAA kinetic parameters in a retrospective cohort of PD patients, also investigating whether CSF total protein content influences such associations.MethodsStudy cohort included cognitively unimpaired PD (PD-CN, n = 40), PD with mild cognitive impairment (PD-MCI, n = 44), and PD with dementia (PDD, n = 10) with available clinical assessment at baseline. Among them, n = 28 PD-CN and n = 31 PD-MCI patients had 2-year follow-up, and CSF biomarkers reflecting pathophysiological pathways other than synucleinopathy.ResultsIn PD-MCI, αS-SAA time-to-threshold (TTT) is associated with longitudinal changes in Mini-Mental State Examination. The association is stronger when accounting for CSF total protein concentration.ConclusionsαS-SAA TTT may represent a prognostic factor for cognitive decline in PD-MCI.
