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

Biomolecular condensates (BMCs) are central to subcellular organization, influencing processes from RNA metabolism to the stress response and amyloid pathologies. Despite their near ubiquity, we still do not fully understand how the primary sequence of biomolecules influences the formation and dynamics of condensates. Here, we examine how cationic amino acid identity shapes the properties of protein-RNA coacervates. Using engineered recombinant proteins, we find that phase boundaries depend on both amino acid identity and protein net charge. Despite identical charge at physiological pH, arginine promotes a higher salt resistance in vitro, enhanced condensate formation in
