A Bertrand model with Brownian motion and behavioral errors.
Article in Scientific reports, 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
This paper extends a random version of Bertrand model with Brownian motion. The model can be used to adjust price with changing economic environment, as it can serve to capture the behaviours of managers who seek to avoid errors in identifying the optimal response in dynamic price settings within their respective markets. The equilibrium of a stochastic game model is further discussed with the solution solved by Hamilton-Jacobi-Bellman equations, and the equilibrium exhibited fluctuations in the numerical simulation, with a constant value being observed. Finally, the model shows that organisations that are less efficient at managing errors, particularly those with a smaller market share, are more susceptible to failure.
