Embryotoxicity and Cardiotoxicity Assessment of Chemical Compounds Using Eggs of Lymnaea stagnalis.
Article in Current protocols, 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
There is a paucity of invertebrate models for the assessment of general and organ-specific toxicity caused by chemicals, such as chemotherapeutics and environmental pollutants. To address this, we have established the embryo of Lymnaea stagnalis (great pond snail) as a simple and rapid model to assay toxicity in a medium-throughput manner. For measuring general toxicity, we have successfully repurposed Alamar Blue dye to assay physiological activity of the embryos. Due to the transparent nature of the L. stagnalis eggs, we have employed a microscope-based phenotypic assay to determine cardiotoxicity. Furthermore, we have previously shown that this model can be used to test cardioprotective strategies to overcome toxicity indued by cancer chemotherapeutics. Due to similarities of the L. stagnalis heart with that of a vertebrate heart, combined with the advantages of easy handling, L. stagnalis eggs serve as an emerging model for embryotoxicity and cardiotoxicity screening of pharmaceutical agents and environmental pollutants. © 2026 Wiley Periodicals LLC.
