Droplet removal by capillary lifting.
Article in Communications physics, 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
The removal of liquid droplets from solid surfaces is central to cleaning, coatings and oil recovery. While dewetting in binary fluid systems has been widely studied, the mechanisms governing dewetting in ternary systems involving an immiscible working liquid remain poorly understood. Here we show that a rising working liquid can capillary lift droplets into bridges extending from the solid surface to the air interface, leading to full, partial, or no droplet removal. Our theoretical model predicts, and experiments confirm, that the effectiveness of droplet removal can be tuned by manipulating the droplet contact angle with the solid and the interfacial tensions at play in the system. Significantly, dewetting can be enhanced by employing working liquids with high interfacial tension, in contrast to common surface cleaning strategies where surfactants are used to reduce interfacial tension. Our findings suggest new avenues for droplet manipulation, especially if concerned with reduced resources and a more sustainable environmental impact.
