Major heat wave in the North Atlantic had widespread and lasting impacts on marine life.
Review 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
Marine heat waves (MHWs) are increasing in frequency and intensity, but wider effects are unexamined in the North Atlantic, and there are uncertainties regarding the spatial scale, magnitude, and persistence of MHWs' impacts on ecosystems. We show that a sudden and strong increase in the frequency of MHWs in and after 2003 was linked to widespread and abrupt ecological changes. This upheaval spanned multiple trophic levels, from unicellular protists to whales. Every examined region showed a reorganization from species adapted to colder, ice-prone environments to those favoring warmer waters and the event's impacts altered socioecological dynamics. This review provides evidence for large-scale connectivity across ocean basins. However, it reveals that the magnitude of ecological impacts seems to vary among events highlighting key knowledge gaps for predicting ecosystem responses to MHWs. Understanding the importance of the subpolar gyre and air-sea heat exchange will be crucial for forecasting MHWs and their cascading effects.
