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
Voronoi-based non-periodic porous structures resemble trabecular bone and are widely used in bone scaffold design. To clarify the influence of strut-diameter morphology on compressive mechanical properties, two Voronoi porous structures with identical porosity, namely uniform-strut and non-uniform-strut structures, were constructed. Their quasi-static compressive and compressive-fatigue behaviors were analyzed using the finite element method. The results showed that the uniform-strut structure had a more homogeneous stress distribution and higher stiffness in the linear elastic stage. The non-uniform-strut structure exhibited higher load-bearing capacity and energy absorption during compression failure. Under compressive fatigue loading, the uniform-strut structure generally showed a longer fatigue life. The uniform-strut structure is suitable for implant scaffolds and prostheses under the conditions of long-term cyclic loading and controllable mechanical matching; the non-uniform filament diameter structure is more suitable for applications under the conditions of impact resistance and energy absorption buffering. These results provide a reference for the selection and optimization of Voronoi biomimetic porous structures under different service requirements.
