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
Introduction: Most orthopedic implants for fracture fixation and joint replacement are commonly tested on artificial bones. Polyurethane foam is one of the most frequently used synthetic bone materials for mimicking human trabecular tissue. The study aimed to examine the compressive and tensile behavior of polyurethane foams mimicking trabecular tissue in artificial human femurs and assess their potential to replicate the osteoporotic type of human bone tissue. Materials and methods: Two types of SYNBONE femur models, one of normal density (model 2350) and one of lower density (model LD2350), and three types of Sawbones femur models (models 1130-21-8, 1130-21-3, and 1130-192) were investigated. Polyurethane foams were extracted as slices cut in the coronal plane from the femoral head. Cuboid samples were cut in three directions and uniaxial tested to identify compressive and tensile properties, including elastic modulus, Poisson's ratio, yield limit, and ultimate strength. Results: The ANOVA test revealed that only SYNBONE LD2350 trabecular tissue exhibits anisotropy properties ( Conclusion: The obtained results are within the ranges suggested by other authors for mimicking osteoporotic human tissue. The presented data broadens the range of data on mechanical properties provided by the producers. These data can serve as a reference for research using composite femurs made of these particular polyurethane foams for conducting biomechanical studies and validating accompanying numerical simulations.
