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

Achieving toughness, notch insensitivity, and self-healing within a single thermoplastic polyurethane (TPU) system is challenging. Hard domains formed by hydrogen-bonded urethane linkages provide mechanical strength but limit the chain mobility needed for healing, while soft domains enable elasticity but are more vulnerable to damage. We propose a soft-segment modification strategy that incorporates α,ω-hydroxyl end-functionalized polyacrylates into conventional TPU structures. Unlike our previous systems based on linear-alkyl acrylates (i.e., n-butyl acrylate), introducing branched-alkyl acrylic soft segments (i.e., 2-ethylhexyl acrylate) generate side-chain architectures whose segmental dynamics respond more sensitively to temperature. This enhanced thermal responsiveness promotes thermally activated chain mobility and more uniform stress distribution, all without compromising the mechanical contribution of the hard domains. As a result, the acrylic TPUs display high toughness (186 MJ·m
