Extraction, characterization, and toxicity evaluation of levan from marine bacterium Priestia aryabhattai LEV207 using brine shrimp model.
Article in Archives of microbiology, 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
Levan is an exopolysaccharide produced by microorganisms and has potential uses in the food and medical sectors. However, in natural habitats, its production is limited by nutrient scarcity and unfavorable environmental conditions. The present study is focused on enhancing levan production via a factor-by-factor optimization approach using the marine isolate Priestia aryabhattai LEV207. The impact of different media components and culture conditions on levansucrase production and bacterial cell growth was systematically investigated. Sucrose and yeast extract were identified as key inducers for levansucrase synthesis. The optimum conditions for maximum enzyme activity were 30 °C and pH 5.0, in the presence of 100 mM CaCl
