Digital Printing of Photoreversible Protective Films.
Article in Macromolecular rapid communications, 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
Temporary protective coatings are widely used in modern production processes. Yet, while highly desirable, their high-resolution printing and stimuli-responsive removal remain challenging. To address this need, we introduce acrylate-based photopolymerized and photoreversible protective films that can be applied using aerosol jet printing. The acrylate films were formulated using aqueous solutions of a photocleavable diacrylate cross-linker and acrylated macromers. To form films, the precursor solution was cured with 405 nm light for 120 s. The films were subsequently removed via photodegradation upon exposure to 365 nm light within minutes to hours depending on film thickness and light intensity. The addition of a polyethyleneimine-based adhesion promoter, Lupasol WF, led to significant improvement of adhesion to industry-relevant surfaces. Quantification using a rheometer in extensional mode showed a fracture energy of the films 3.25x higher than without the adhesion promoter. The protective films were applied using aerosol jet printing, enabling a feature resolution below 30 µm and a spatially selective treatment of metallic surfaces with Paris oxide. These results demonstrate how photopolymerized and photoreversible polymer networks enable temporary protective coatings in industry-relevant applications.
