Viscoelastic cell model of sorting in the dictyostelium discoideum slug.
Article in PloS one, 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
Cell sorting and differential motion are key processes in the life cycle of Dictyostelium discoideum (Dd) and many other organisms. Here we develop a mathematical model and investigate the processes with computer simulations. The slug stage of Dd is modeled with ellipsoidal cells of two types which have viscoelastic properties. Using the force-based model we find that when the two cell types have different strengths of motive forces and or different degrees of directionality one cell type sorts to the front of the slug. These findings are consistent with previously published results using a different model formation. When one cell type is more directed than the other it will consistently sort to the front of the slug. Likewise, but less efficiently, when one cell type exerts greater motive forces than the other it will sort to the front of the slug. The most efficient and robust cell sorting due to differential motion is when both methods are employed.
