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

Progressive supranuclear palsy (PSP) is a neurodegenerative disease characterized by abnormal accumulation of the protein tau in the brain, leading to motor and cognitive symptoms that vary between individuals. The reasons for this clinical heterogeneity are unknown. Here we show that distinct molecular forms of tau, particularly high molecular weight (HMW) assemblies, differ in abundance and biological activity across PSP brains. By combining biochemical examination, seed amplification assays, proteomic profiling, and spatial transcriptomics, we identify that HMW tau species drive the strongest aggregation activity in the primary motor cortex. Cases with high tau seeding activity display molecular signatures of altered immune and metabolic pathways. These findings reveal that tau seeding activity reflects underlying molecular heterogeneity in PSP and suggest that measuring 4R-tau seeding capacity could help stratify patients and guide the development of targeted therapeutic approaches.
