Acoustic Emissions from Grey Glacier, Chilean Patagonia: dataset of infrasound measurements.
Article in Scientific data, 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
Calving is a critical process contributing to ice mass loss in tidewater and lake-terminating glaciers, with significant implications for freshwater input, glacier dynamics, and climate change. Infrasound emissions generated by calving events represent a powerful tool for monitoring, quantifying, and understanding the mechanisms that drive glacier retreat. In this study, we present the first acoustic dataset collected over a six-day period during the austral summer at Grey Glacier, located in Torres del Paine National Park, Chile. We provide a detailed description of the instrumentation setup, data acquisition procedures, and signal processing methodologies. By applying high-sensitivity infrasound array processing techniques, we demonstrate that coherent signals generated by calving events can be reliably extracted from the acoustic data, despite environmental conditions, such as strong winds that affect infrasound propagation. This dataset represents a valuable resource for advancing research on cryosphere dynamics and offers practical applications for the glaciological and geophysical communities.
