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

Extrusion-based Bioprinting is a key technology in biofabrication, yet the choice of extrusion method is often limited to established techniques built into most bioprinters, limiting the print fidelity and more demanding applications like printing material gradients. In this technical report we compare the emerging method of progressive cavity pump with established technologies such as pneumatic extrusion and syringe pump-based printing setups. The three methods were compared for their accuracy and precision in extruding 35% Pluronic F127, followed by test simulating different flow profiles, material dependency and ability to transfer between hardware setups. The progressive cavity pumps showed the most advantageous behavior for gradient printing, with the syringe pumps needing more iterations for stable extrusion and the pneumatic extrusion enabling high-volume extrusion but showing lower precision. This was further shown with the printing of different gradients.
