Polymorphic Transformations of Pharmaceutical Materials Induced by Mechanical Milling: A Review.
Review in Pharmaceutics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
A review of the literature on polymorphic transformations by milling on pharmaceutical materials was carried out. The available information on 18 pharmaceutical materials was compiled. In particular, when data are available, the starting and final crystalline forms, their enantiotropic or monotropic relationship, the glass transition temperature of the compound and its melting temperature, the experimental observation of a transient or partial amorphization of compounds, and the transformation kinetics make it possible to suggest a two-step transformation mechanism. First, an amorphization occurs under milling of the starting polymorphic form. Secondly, a recrystallization of the amorphous form occurs towards the final form. The observed transformation kinetics are due to the fact that the recrystallization of the amorphous material towards the final form depends on the accidental formation of a cluster of this form during milling. Moreover, the observation of the transient amorphous form depends on the relative position of the glass transition temperature of the material with respect to the milling temperature. This mechanism seems to be independent of the enantiotropic or monotropic character of the polymorphic forms involved in the transformation.
