The extent of protease resistance of misfolded prion protein is highly dependent on the salt concentration.

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
Transmissible spongiform encephalopathies are neurodegenerative diseases caused by prions in mammals. An aberrantly folded protein (PrP(Sc)) is the main component of these proteinaceous infectious particles. Prions exhibit strong resistance to protease digestion, which is typically exploited for biochemical discrimination from its native cellular form (PrP(C)). This classical feature has been partially challenged by the isolation of sizeable amounts of protease-sensitive PrP(Sc) isoforms that self-propagate in vivo. Here, we report that the degree of PrP(Sc) protease resistance is highly dependent on the concentration of salt in the solution. Similar changes were observed in PrP(Sc) obtained from different strains and species. Strikingly, the effect of salt is reversible and is associated with changes on the size of PrP(Sc) particles, but surprisingly, the more protease-sensitive species consists of a larger size. These findings shed light on the mechanistic aspects of prion proteolysis and should be considered when assessing samples of biomedical relevance.
