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

Epoxy thermosetting polymers are widely used in industrial applications. In their synthesis, amines are commonly employed as curing agents for epoxy monomers bearing glycidyl groups. Although the degradation of amine-cured epoxy thermosets has been studied, the selective recovery of parent amines as reusable organic substrates remains insufficiently developed, largely due to the difficulty of achieving selective main-chain cleavage. Herein, we report the degradation of epoxy thermosets cured with bis(arylamines) for 150 or 190 °C, which serve as stable and rigid curing agents, via cleavage of both carbon-oxygen and carbon-nitrogen bonds in the polymer backbone. The use of NaOH in 1,3-dimethyl-2-imidazolidinone, in combination with Ca(OH)
