Dramatic ENSO related Southwestern Atlantic ecosystem shifts.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
ENSO (El Niño Southern Oscillation) events are becoming more frequent and more intense as climate change continues. Although ENSO effects are known to propagate into the southwest Atlantic, knowledge of how these anomalies result in ecological impacts is yet to be documented. A 3600 km transect in the southwest Atlantic from the Falkland Islands (Malvinas) to Tristan da Cunha during La Niña (March 2018) found a more abundant and speciose seabird assemblage, with more filter-feeding seabird and cetacean species, and a shallower and more concentrated pelagic biomass, than a near identical transect during El Niño (March 2019). Changes in wind and sea surface temperature anomalies correlated, through a one-to-three-month lag, to the peak BEST (Bivariate ENSO Index) index. Stronger winds and greater near surface ocean mixing are for the first time described as mechanisms through which ENSO events can propagate across the southwest Atlantic Ocean basin to alter pelagic ecosystem structure and communities.Main Text.
