High pressure, a tool to switch between soluble and fibrillar prion protein structures.
Article in Communicative & integrative biology, 2012. 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
The native soluble as well as different aggregated states of recombinant prion proteins are highly sensitive to high pressure. On the one hand, its application to the native α-helical protein induces reversibly a metastable structure that relaxes to amyloid fibrils after prolonged incubation. On the other hand, its application to synthetic prion amyloid fibrils leads to partial disaggregation into native monomers as well as to proto-filaments that have lost several amyloid features. In addition, heat-induced β-sheet prion protein aggregates are dissolved and revert into α-helical monomers by applying high pressure. This profound pressure sensitivity of prion protein structure is explained by large volume differences of the different structural states. Hence, pressure appears as a suitable thermodynamic parameter for exploring the highly complex conformational landscape of prion protein. Its further analysis should help identifying prion protein structural states that are on the pathogenic pathway.
