A protease-precursor system drives synergistic antagonism in haloarchaea.
Article in mBio, 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
Antagonistic competition is a crucial survival strategy for microorganisms sharing ecological niches, playing a key role in shaping microbial communities and influencing biogeochemical cycles. Here, we report the first extracellular serine protease-dependent synergistic antagonism in archaea: a collaboration between an extracellular protease-producing strain and a precursor protein-producing strain. The serine protease secreted by the former cleaves the precursor protein released by the latter, generating an antibacterial effector molecule. This synergistic antagonism also occurs across domains (between halophilic bacteria and archaea), indicating broad ecological relevance. Using mass spectrometry and inhibition assays, we identified HFX_0892-from the model haloarchaeon
