Predation threat affects isotope ratios of planktonic consumers.
Article in Oecologia, 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
The analysis of stable isotopes of carbon and nitrogen is widely used in ecological investigations. However, sources of variation in isotope ratios of animals are far from being identified, which may bias the interpretation of the results. It has been suggested that stress is a factor that affects isotope ratios and trophic enrichment in animal bodies. Here, we tested the hypothesis that stress due to exposure to a predation threat affects metabolic processes that ultimately result in altered isotope composition of threatened prey. We found that both the nitrogen isotope composition (δ
