Deciphering the mechanisms of oxygen transfer into a wine bottle.
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
This study aims to deepen the understanding of how oxygen transfers through wine bottle closures and their chemical reactivity and kinetics during storage. A miniaturized bottle system was designed to enable measurements with or without model wine. Different physical and chemical mechanisms, each with its own kinetics, were revealed through oxygen permeability measurements. Four main mechanisms were identified, each occurring over different timescales. In the first days of storage, rapid equilibrium is established between the gas and liquid phases of the model wine. During the early months, oxygen diffuses from the cork cells into the gas phase in the system. Phenolic compounds are then extracted from the cork and react with the oxygen released from the sealing system into the liquid phase, leading to a decrease in oxygen content over several months. Ultimately, long-term oxygen permeation through the closure results in a gradual, continuous increase in oxygen content within the mini-bottle system.
