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
Background: Understanding the non-linear mechanical behavior of human bone is critical for improving orthopedic modeling and developing personalized treatment strategies. The Mooney-Rivlin model, traditionally used in soft matters, has been extended to capture the complex stress-strain relationships of hard biological materials like bone. Objective: To apply the Extended Mooney-Rivlin model to human bone specimens and quantify regional variations in mechanical parameters, with the goal of improving finite element simulations and biomechanical interpretations. Participants and setting: The study analyzed bone specimens from the proximal femur as well as the midshaft, distal, and proximal sections of long bones in the lower limb, based on data obtained from the literature. Methods: Experimental stress-strain data were collected from bone samples subjected to uniaxial loading. The Extended Mooney-Rivlin model was fitted to the data to extract four key parameters: Results: The model demonstrated strong goodness-of-fit across all specimens ( Conclusions: The Extended Mooney-Rivlin model effectively captures regional variations in bone mechanics, with clear distinctions between cortical and trabecular bone behavior. These findings support its application in advanced biomechanical modeling and suggest new directions for personalized orthopedic treatment. Future work should explore the influence of age, bone mineral density, and pathological changes on these mechanical parameters.
