Coastal methane emissions driven by aerotolerant methanogens using seaweed and seagrass metabolites.
Article in Nature geoscience, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Methanogenesis is thought to be limited to strictly anoxic environments. While oxygenated oceans are a known methane source, it is argued that methane production is driven by methylphosphonate-degrading bacteria and potentially other sources rather than by methanogenic archaea. Here we develop in situ monitoring and ex situ manipulation experiments, combined with biogeochemical, metagenomic and culture-based experiments, to show that methane is rapidly produced by archaea in frequently oxygenated sandy sediments. We show that methane emissions from sandy sediments are not inhibited by repeated oxygen exposure and suggest the activity is driven by aerotolerant methylotrophic methanogens (primarily Methanosarcinaceae) broadly distributed in the surface layers of sandy sediments. Moreover, we show that methane emissions are driven by methylated seaweed and seagrass metabolites, revealing a feedback loop between primary production and greenhouse gas emissions.
