Research on the preparation of antimicrobial material based on thermoplastic polyurethane and drug release control.

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
It's crucial of antimicrobial properties in materials is growing as people desire to live healthier. The purpose of this work was to use thermoplastic polyurethane (TPU) as a matrix to produce an antimicrobial material with a tunable drug release rate. Filaments with a diameter of 1.75 ± 0.08 mm were prepared by hot-melt processing technology utilizing TPU, the modifier polyethylene oxide (PEO) and ciprofloxacin hydrochloride monohydrate (CPFX) as raw materials. The corresponding models were then printed using fused deposition type (FDM) 3D printing for performance testing. Results demonstrate the uniform fiber morphology and strong mechanical properties of the four samples, each of which was composed of a different ratio of components. The addition of PEO caused a change to the drug release mechanism, increased the material hydrophilicity, and generated extra pores during the dissolution process. This composite exhibited sustained antimicrobial activity even after 21 days of rotary immersion, as shown by in vitro dissolution and zone inhibition tests.
