Regional bone density patterns of the tibial plateau: implications for finite element analysis.
Article in Frontiers in bioengineering and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The tibial plateau has different anatomical regions and heterogeneous bone densities. Most finite element simulation (FEM) studies of tibial plateau fracture fail to account these regional variations, which may significantly influence biomechanical behavior. This study aimed to quantify the regional density profile of the tibial plateau using Hounsfield Units (HU) from computed tomography (CT) scans and explore associations between density, age, and sex. We developed a novel measurement protocol to compare HU values of the subchondral bone and cancellous bone in eight different regions of the tibial plateau. Results demonstrated that patient age and female sex were associated with reduced bone density. Subchondral bone and medial bone had significantly higher density than metaphyseal and lateral bone, respectively. This findings could have implications on orthopedic modeling of tibial plateau fractures using FEM. Current FEM should consider distinct regions in tibial plateau to improve accuracy. Conclusion: Tibial plateau heterogenous bone density distribution could contribute to explain the low predictive accuracy in FEM models.
