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

The ability of a single polypeptide sequence to grow into multiple stable amyloid fibrils sets these aggregates apart from most native globular proteins. The existence of multiple amyloid forms is the basis for strain effects in yeast prion biology, and might contribute to variations in Alzheimer's disease pathology. However, the structural basis for amyloid polymorphism is poorly understood. We report here five structurally distinct fibrillar aggregates of the Alzheimer's plaque peptide Abeta(1-40), as well as a non-fibrillar aggregate induced by Zn(2+). Each of these conformational forms exhibits a unique profile of physical properties, and all the fibrillar forms breed true in elongation reactions under a common set of growth conditions. Consistent with their defining cross-beta structure, we find that in this series the amyloid fibrils containing more extensive beta-sheet exhibit greater stability. At the same time, side chain packing outside of the beta-sheet regions contributes to stability, and to differences of stability between polymorphic forms. Stability comparison is facilitated by the unique feature that the free energy of the monomer (equivalent to the unfolded state in a protein folding reaction) does not vary, and hence can be ignored, in the comparison of DeltaG degrees of elongation values for each polymorphic fibril obtained under a single set of conditions.
