Projectile deformation on human bone and on a polyurethane simulant.
Article in International journal of legal medicine, 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
Polyurethane bone simulants are often used in ballistic experiments, within a forensic and medico-legal context and elsewhere. This study compared the degree of deformation of projectiles fired at human bone to projectiles fired at a polyurethane bone simulant. Ductile 5.5 mm spheres were propelled with a mean velocity of 279 m/s and fired at both freshly embalmed human cranial bone samples and at polyurethane bone simulant samples. The spheres deformed more when perforating the human samples than when perforating the polyurethane samples. As a result, it is questionable to use such simulants for medico-legal and forensic studies where aspects such as bullet deformation and bullet path reconstruction are important. The degree of deformation did not seem to be influenced by overall cranial bone thickness, nor by the overall thickness of the polyurethane simulant. With human bone, a positive relation is observed between projectile deformation and thickness of the tabula externa.
