Format-Preserving Reduction of Canonical Nonlinear Models.
Article in Bulletin of mathematical biology, 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
The recent upward trend in the size of mathematical models in the biomedical sciences offers novel opportunities and challenges. The latter are partially technical, for instance, in terms of computational efficiency and the need of vastly increased parameter determination, and partly conceptual, as large models make it more difficult to discern which variables are the key drivers of the model dynamics. The article proposes a model size reduction strategy that replaces differential equations with their corresponding nullclines. The result is an approximation whose quality depends on numerous aspects of the analyzed system. In the case of canonical S-systems and Lotka-Volterra models, the proposed reduction is essentially always feasible and retains their mathematical format, thereby facilitating sequential reductions. As these reductions are entirely formulaic, they are ideally suited for automation, which could systematically lead to models of optimally reduced sizes.
