Computationally Efficient Polarizable MD Simulations: A Simple Water Model for the Classical Drude Oscillator Polarizable Force Field.
Article in The journal of physical chemistry letters, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
An improvement in the computational efficiency of polarizable force field simulations is made through the development of a polarizable Drude water model, SWM3, in combination with the use of Lennard-Jones Particle Mesh Ewald (LJPME) for the treatment of long-range LJ interactions. The experimental bulk properties, density, heat of vaporization, dielectric constant, and self-diffusion constant of the SWM3 model are accurately replicated at ambient condition. The temperature dependence of the bulk properties is also captured except for the density. Microscopic properties, such as hydration free energy, dimer properties, and binding energies of clusters are well represented. The SWM3 model is ∼40% faster than the SWM4 water model traditionally used with the Drude force field, and use of LJPME offers an additional 30% speedup in heterogeneous systems. This combination makes the SWM3-based Drude model only 2.6-fold slower than the TIP3P-based additive simulations.
