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

Hyperpolarization of small peptides by parahydrogen-induced polarization (PHIP) to increase the sensitivity of nuclear magnetic resonance (NMR) techniques is well established, while its application to larger biopolymers is still a mainly unexplored area. A particular challenge is the presence of folding-essential disulfide bridges. They tend to form metal complexes, thus hampering catalytic hydrogenation, a prerequisite for PHIP. We applied the PHIP technique to enhance NMR signal intensity in cystine-knot miniproteins─highly ordered peptide architectures covalently stabilized by three disulfides. To achieve PHIP, we introduced an l-propargyl tyrosine label at different positions in three synthetic open-chain variants of a natural trypsin inhibitor MCoTI-II. For the folded cystine knot, we observed NMR signal enhancements of up to 499 in methanol, 307 in a D
