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

Spontaneous aggregation of amyloid beta (Aβ) proteins leading to the formation of oligomers and eventually into fibrils has been identified as a key pathological signature of Alzheimer's disease. The structure of late-stage aggregates have been studied in depth by conventional structural biology techniques, including nuclear magnetic resonance, X-ray crystallography, and infrared spectroscopy; however, the structure of early-stage aggregates is less known due to their transient nature. As a result, the structural evolution of amyloid aggregates from early oligomers to mature fibrils is still not fully understood. Here, we have applied atomic force microscopy-infrared nanospectroscopy to investigate the aggregation of Aβ 16-22, which spans the amyloidogenic core of the Aβ peptide. Our results demonstrate that Aβ 16-22 involves a structural transition from oligomers with parallel β-sheets to antiparallel fibrils through disordered and possibly helical intermediate fibril structures, contrary to the known aggregation pathway of full-length Aβ.
