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
Antarctic heatwaves driven by atmospheric rivers are emerging as high-impact extremes, yet the role of climate change in amplifying such events remains uncertain. Here we investigate the climate change contribution to the March 2022 East Antarctic heatwave using pseudo-global warming experiments with the snow-atmospheric coupled model CRYOWRF. By comparing present-day and preindustrial storylines, we identify that under current climate, cloud and water-vapor radiation feedbacks non-linearly amplify near-surface warming by up to 10 °C (equivalent to 25% of the amplification) relative to preindustrial conditions. These feedbacks are likely underrepresented in global climate models due to their use of hydrostatic dynamics, and poor cloud representation over coarse resolutions. Future warming further intensifies this amplification, particularly along the coast, where firn air content is depleted, meltwater percolates, and ice lenses thicken. Such melting conditions threaten to accelerate surface mass loss and destabilize the fringing ice shelves. Our results reveal a key amplification pathway for Antarctic extremes, with potentially far-reaching implications for ice-sheet stability.
