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

We previously reported that peptides can drive diffusion-limited aggregation (DLA) of silver nanoparticles (AgNPs) into complex, fractal assemblies, but the mechanism behind this behavior remained unclear. In this study, we dissect how surface ligand chemistry governs this process: not merely by mediating interparticle interactions but by enabling structural transformation of the nanoparticle cores themselves. Using a panel of nine ligands spanning phosphine, thiolate, and polyphenol classes, we systematically examine how ligand identity dictates aggregation dynamics, redox behavior, and structural outcomes. Our findings reveal that aromatic phosphine ligands, especially bis(
