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

Solid-state NMR spectroscopy is increasingly applied to structural and dynamics studies across a broad range of chemical, material, and biological systems. Although sensitivity has traditionally been a major limitation, the recently developed MAS cryoprobe has been shown to substantially overcome this challenge. Its ability to enhance the signal-to-noise (S/N) ratio without requiring sample freezing makes it particularly attractive for investigating non-isotropic systems, including soft materials (e.g., hydrogels), semi-solids (e.g., membrane mimetics) and rigid solids (e.g., amyloid fibrils). In this study, we report on the enhanced sensitivity of solid-state NMR experiments on α-synuclein fibrils using a MAS cryoprobe. Nearly an order-of-magnitude improvement in S/N was observed in CPMAS, refocused-INEPT and 2D
