Assessment of Local Pelvic Bone Volumetric Density and Cortical Thickness Using Multi-Energy Bi-Planar Radiography.
Article in Journal of musculoskeletal & neuronal interactions, 2025. 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
objectiveThis study presents a method to determine the volumetric density of pelvic bone and cortical bone thickness along critical regions of the S2 alar-iliac (S2AI) screw trajectory using bi-planar multi-energy X-ray (BMEX).
methodsSimulated BMEXs were generated from CT data from eight patients, with coordinate matching linking pixels to voxel density values. This dataset included pixel attenuation values, coordinates as independent variables, and voxel attenuation values (Hounsfield Units, HU) as the dependent variable for training a random forest regressor model.
resultsThe trained model revealed adequate trabecular bone density prediction (root mean square error: 32.8 mg/cm
conclusionsThe improved prediction of bone density and the capability to estimate cortical bone thickness signify a significant advancement towards a comprehensive modality for predicting bone quality in implant placement planning.
