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

Prions are self-propagating, infectious protein conformations. The mammalian prion, PrP(Sc), responsible for neurodegenerative diseases like bovine spongiform encephalopathy (BSE; "mad cow" disease) and Creutzfeldt-Jakob's disease, appears to be a beta-sheet-rich amyloid conformation of PrP(c) that converts PrP(c) into PrP(Sc). However, an unequivocal demonstration of "protein-only" infection by PrP(Sc) is still lacking. So far, protein only infection has been proven for three prions, [PSI(+)], [URE3] and [Het-s], all of fungal origin. Considerable evidence supports the hypothesis that another protein, the yeast Rnq1p, can form a prion, [PIN(+)]. While Rnq1p does not lose any known function upon prionization, [PIN(+)] has interesting positive phenotypes: facilitating the appearance and destabilization of other prions as well as the aggregation of polyglutamine extensions of the Huntingtin protein. Here, we polymerize a Gln/Asn-rich recombinant fragment of Rnq1p into beta-sheet-rich amyloid-like aggregates. While the method used for [PSI(+)] and [URE3] infectivity assays did not yield protein-only infection for the Rnq1p aggregates, we did successfully obtain protein-only infection by modifying the protocol. This work proves that [PIN(+)] is a prion mediated by amyloid-like aggregates of Rnq1p, and supports the hypothesis that heterologous prions affect each other's appearance and propagation through interaction of their amyloid-like regions.
