A Systematic Comparison of Alpha-Synuclein Seed Amplification Assays for Increasing Reproducibility.
Review in Annals of clinical and translational neurology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Seed amplification assays (SAAs) enable ultrasensitive detection of misfolded α-synuclein across biofluids and tissues. Yet, heterogeneity in protocols limits cross-study comparability and clinical translation. Here, we review α-synuclein SAA methods and their performance across various biological matrices. We catalog key variables (e.g., human recombinant α-synuclein variants, buffers, salts, beads, shaking, incubation temperature) and outline pre-analytical factors that shape outcomes. We propose a prioritized framework of key analytical and pre-analytical variables most likely to influence assay reproducibility and clinical interpretation. We also outline minimal reporting criteria and practical quality-control checkpoints, and recommend multicenter interlaboratory proficiency testing as essential steps to accelerate the robust clinical and research implementation of α-synuclein SAAs.
