Retention of noble gases in the deep Earth: Kinetic trapping or stable bonding?
Article in Science advances, 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 bonding potential of noble gases in high-pressure silica-bearing solids and melts remains debated, yet it is a central question for understanding their retention behavior and evaluating the role of silicate-bearing phases in the transport and storage of noble gases originally present in the atmosphere. Here, we assess the chemical behavior of noble gases in three silicates: quartz, seifertite, and perovskite. Using the electron localization function and Bader charge analysis, we find no evidence of stable covalent or ionicbonding. The very slow intracrystalline diffusion of heavy noble gases governs their trapping in silicates during crystal growth. Noble gases are more likely to reside in melts or grain boundaries than in silicate crystal lattices.
