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

2-Pyrone-4,6-dicarboxylic acid (PDC) is a lignin-derived biometabolic intermediate that serves as a versatile monomer for the development of sustainable polymers. In the present study, a bio-based polyesteramide, P-(PDC-BiOx), was successfully synthesized via the atom-economical ring-opening polyaddition of PDC and 2,2'-bis-(2-oxazoline). The thermal, crystalline, and mechanical properties of the resulting polymer were fully characterized, revealing a completely amorphous backbone with a fracture stress of 10.34 MPa. The marine biodegradability behavior was investigated under both surface and deep seawater conditions, demonstrating a clear correlation between material morphology and biodegradation rate. The experimental results demonstrated that, in surface seawater, the electrosprayed microparticles degraded more rapidly than the hot-pressed film, although both eventually reached a comparable extent of degradation. In comparison, in deep seawater, the electrosprayed microparticles achieved approximately 30% biodegradation within 45 days, which was higher than that of the hot-pressed film. Overall, PDC polyesteramides are promising biomass-derived polymers with straightforward accessibility and potential marine biodegradability.
