Bioinspired hierarchical fibre bundles from microfluidics for nerve regeneration.
Article in Bioactive materials, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Fibre-shaped scaffolds have demonstrated value in nerve tissue engineering because of their ability to direct cell alignment and remodel intrinsic fibrous tissues. Research in this aspect focuses on the creation of microfibres with nerve-mimicking morphology and spatial neurocyte guidance to improve the regeneration effects. Here, inspired by the anatomical structure of the nerve that is composed of parallelly assembled nerve fibres, we present novel hierarchical fibre bundles from microfluidics for peripheral nerve regeneration. The GelMA/alginate filaments encapsulated in hydrogel microfibre shells were consecutively generated from the coaxially assembled capillary microfluidic device, and their composition and morphology could be further tuned by changing the microchannel and fluid constructions. Based on the resultant microfibres, we have demonstrated that they could provide a biomimicking cell culture environment and promote the formation of nerve bundles. In addition, the hierarchical fibre bundles showed an improved regeneration capability of sciatic nerves when they were transplanted into sciatic nerve defect SD rat models. Thus, hierarchical fibre bundles are potentially valuable for clinical peripheral nerve regeneration.
