A novel photocurable pullulan-based bioink for digital light processing 3D printing.

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
Digital light processing has significant advantages, such as high repeatability, low failure rate, and no extrusion shear force. To make it possible to print complex structures with high resolution, the consecutive development of photocurable ink materials is indispensable. In this work, photo-functionalized pullulan (Pul-NB) was prepared by introducing norbornene groups into pullulan chains, and an ink material suitable for photocurable printing was prepared by thiol-ene click reaction. The rheology, water absorption, and mechanical properties of the Pul-NB precursor solution and photocurable hydrogel were investigated. The optimal composition of Pul-NB ink for three-dimensional (3D) printing was obtained by adjusting the degree of substitution, Pul-NB concentration, and thiol crosslinking agent. This novel bioink for digital light processing 3D printing showed good printability and high shape fidelity. This ink material provides an excellent alternative for printing biomimetic soft tissue organs, high-throughput tissue models, soft robots, etc.
