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
Cranial bone regeneration requires coordinated interactions among host cells, extracellular matrices, and the local biomechanical environment to restore both mineralized tissue and structural protection of the brain. Mineralized collagen-glycosaminoglycan (MC-GAG) scaffolds recapitulate key features of native bone matrix and have demonstrated osteogenic potential in preclinical calvarial defect models; yet, robust, quantitative methods are needed to evaluate defect bridging, mineral density, and microarchitectural maturation in vivo. In vivo microcomputed tomography (microCT) enables nondestructive, three-dimensional (3D) assessment of craniofacial healing with spatial detail sufficient to characterize mineral distribution and structural connectivity across large defects. Here, we describe an integrated workflow that combines scaffold implantation in a rabbit critical-sized calvarial defect model with standardized in vivo microCT imaging and 3D computational rendering. The framework includes scaffold fabrication and preparation, surgical creation of a critical-sized calvarial defect with scaffold placement, and in vivo microCT imaging at a single endpoint (6 months post-surgery). Image datasets are visualized and analyzed using reproducible segmentation software (i.e., ORS Dragonfly) to examine defect repair and extract quantitative intensity- and volume-based metrics, including mineralized tissue volume, mineral density, and microarchitectural parameters. This standardized approach supports objective, image-based comparison of scaffold designs and treatment strategies, facilitating rigorous evaluation of cranial bone regeneration and accelerating the development of bone-regenerative biomaterials. © 2026 The Author(s).
