Protection mechanism investigation of a protective coating on magnesium alloy stents via deformation model construction and the simulation of cellular automata.

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
The most significant challenge facing magnesium alloy stents is their ability to withstand complex deformation during their application. To gain a deeper understanding of the impact of stent deformation on the protective capabilities of the coating, this paper presents an amplified stent deformation model. The models were coated with either a low elongation material-Poly(D, L-lactide) (PDLLA) or a high elongation material-Poly(butylene adipate-co-terephthalate) (PBAT), followed by the application of a rapamycin-loaded PLGA as drug-eluting layer. Coating integrity and thickness were examined via scanning electron microscopy (SEM), while electrochemical impedance spectroscopy and long-term immersion tests assessed corrosion behavior on the deformation model. Finite element analysis using Comsol simulated the stress-strain distribution during compression and tension, and cellular automata (CA) models were employed to simulate the corrosion process. The drug release tests were conducted
