Enhancing Poly-ε-Caprolactone Implant Performance: Synergistic Surface Modifications With Osteon-Like Microstructure, Cold Atmospheric Plasma, and Extracellular Matrix Coating.
Article in Macromolecular bioscience, 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
Surface modifications of polycaprolactone (PCL) implants influence osseointegration by altering cell adhesion, proliferation, and differentiation. Osteon-like microtopography has been shown to enhance these parameters compared to untreated PCL. Additional treatments, such as cold atmospheric plasma (CAP) and extracellular matrix (ECM) coatings, may further improve bioactivity. This study evaluates and compares the osteogenic potential of osteon-like microtopography, CAP treatment on non-microstructured PCL, ECM coating on non-microstructured PCL, and their combination. Modified PCL samples were analyzed for cell adhesion, proliferation, and differentiation using primary human mesenchymal stem cells. Compared to osteon-like microtopography, CAP-treated and ECM-coated surfaces the combination of all three increased cell adhesion by nearly two-fold. Cell proliferation followed a similar trend, with the combination treatment showing the greatest enhancement by day 10. Alkaline phosphatase activity peaked with osteon-like microtopography, while mineralization was maximized with the combination treatment. In summary, the integration of osteon-like microtopography with CAP treatment and ECM coating synergistically improves cell adhesion, proliferation, and differentiation, offering a promising strategy for optimizing PCL implants to improve osseointegration.
