Cation-Assisted Surfactant Templating of DNA at the Air-Water Interface: New Insights into Nucleic Acid Surface Activity.
Article in The journal of physical chemistry letters, 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
DNA, a highly negatively charged polyelectrolyte biomolecule, shows negligible propensity for the air-water interface, as DNA prefers to remain fully hydrated in aqueous solutions. Previous studies have shown that cationic surfactants can complex with DNA at the air-water interface through electrostatic interactions and drive DNA to the interface. Here we show a new mechanism, involving DNA complexes to palmitic acid monolayers in the presence of divalent cations Mg
