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

The development of polymer products with a circular economy lifecycle represents a path to alleviate the growing plastic waste and energy crisis. However, long-standing challenges include synthesis scalability, tunable material performance and the feasibility of chemical recycling from mixed products. Here we developed a facile regioirregular polymerization strategy to access diverse polymer structures from a single monomer via regioselectivity and dynamic covalent bond exchange. We were able to synthesize polyurethanes (PUx, where x represents the percentage of urethane linkages in the polymer) with tailored urethane contents by modulating the reaction time for the regioirregular polymerization of tetramethylene urethane. The resulting PUx products showcase remarkable composition-dependent material performance, illustrating high strength, toughness and gas barriers comparable with commercial plastics. In particular, PU57 exhibits superior adhesive strength, outperforming commercial glues. Notably, these diverse PUx products could be converted back to a single monomer, representing a proof-of-concept process for a 'single monomer ↔ multiple polymers' closed loop.
