Tau catalyzes amyloid-β aggregation and toxicity in a polymorph-dependent manner.

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
Interactions between amyloidogenic proteins are emerging as critical drivers of neurodegenerative diseases. Among others, in Alzheimer's disease (AD) and severe forms of chronic traumatic encephalopathy (CTE), codeposition of tau and amyloid-β (Aβ) leads to worsening of clinical outcomes and disease progression. Despite the importance of such heterotypic interactions, the underlying molecular mechanisms have proven challenging to be established. Here, we investigated the direct interaction between Aβ and tau, combining in vitro reconstruction, and in vivo models. We find that characteristic AD paired helical filament (PHF) and CTE folds catalyze the primary nucleation of Aβ42 in a fold-specific manner with enzyme-like kinetics. In particular, CTE fibrils exhibit the highest catalytic activity and constrain Aβ42 polymorphism, suggesting templating effects. Moreover, PHF and CTE tau fibrils increase Aβ42 toxicity in SH-SY5Y neuroblastoma cells and transgenic
