Effective negative depth in water waves.
Article in Science advances, 2025. 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
Ocean waves have long been a hazard to marine operations, making water wave isolation critical in ocean engineering. Traditional methods suffer from large area requirements, high costs, and incomplete isolation. We design a water wave isolation device using periodic gear arrays (PGAs), which overcomes these drawbacks and achieves perfect water wave isolation across a wide frequency band. Water wave isolation occurs by effectively creating a negative water depth, which fills a major gap in the field of manipulating water waves using metamaterial concept. We demonstrate the water wave isolation of PGAs through analytical methods, simulations, and experiments, proving that effective negative water depth is key to achieving the isolation of water waves. The PGAs perform well across a wide frequency band, with potential applications in port and ocean wave isolation. This discovery enriches water wave manipulation techniques and advances the development of water wave metamaterials.
