Four decades of intensifying Southern Ocean swells along the Pacific coast of the Americas.
Article in Nature communications, 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
Swells generated in the Southern Ocean regularly impact the Pacific coasts of the Americas, with the most energetic events causing severe infrastructure damage, coastal flooding, and loss of life. This study presents a detailed, comprehensive analysis of these high-energy swells along this coastline, characterizing their primary characteristics and examining their variability across multiple timescales. These swells occur most frequently during austral winter, with a considerable proportion also occurring in austral spring and autumn. The Southern Annular Mode exerts a strong influence, with its positive phase (SAM + ) being associated with more energetic swells. Significant positive trends in wave height, power, and occurrence rate along much of the studied coastline in recent decades highlight the increasing risk posed by these swell events. Our findings offer valuable insights for enhancing coastal resilience and informing effective risk management strategies in response to this coastal hazard.
