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

Poly(butylene adipate-co-terephthalate) (PBAT) is an important commercial biodegradable flexible copolyester, which is dependent on the fossil-based terephthalates for production. In the present work, two series of PBAT-mimicking copolyesters are synthesized using lignin-sourced aromatic monomers, i.e., methyl 4-(2-hydroxyethoxy) vanillate and methyl 4-(2-hydroxyethoxy) benzoate, aliphatic dimethyl adipate, and 1,4-butanediol. The greenhouse gas emissions associated with the monomer synthesis are investigated by life cycle assessment, and the solvent usage is evaluated. The copolyesters show reasonably high thermal stability, and tunable glass transition temperature and crystallinity upon varying the aromatic-aliphatic ratio. Aerobic biodegradation experiments of the obtained copolyesters over 90 days show a comparable or even faster biodegradation rate compared to the benchmark polymer PBAT. The oxygen gas barrier of the obtained terephthalate-free copolyester films is effectively enhanced compared to that of PBAT, indicating their potential in flexible food packaging applications.
