A FRAX Experience in Korea: Fracture Risk Probabilities with a Country-specific Versus a Surrogate Model
BACKGROUND Recently, a Korean fracture-risk assessment tool (FRAX) model has become available, but large prospective cohort studies, which are needed to validate the model, are still lacking, and there has been little effort to evaluate its usefulness. This study evaluated the clinical usefulness of the FRAX model, a FRAX developed by the World Health Organization, in Korea. METHODS In 405 po...
متن کاملEpidemiology of fractures in Armenia: development of a country-specific FRAX model and comparison to its surrogate
Fracture probabilities derived from the surrogate FRAX model for Armenia were compared to those from the model based on regional estimates of the incidence of hip fracture. Disparities between the surrogate and authentic FRAX models indicate the importance of developing country-specific FRAX models. Despite large differences between models, differences in the rank order of fracture probabilitie...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Designing an Iran FRAX Model and Defining Intervention and Assessment Thresholds for Osteoporosis
Background and Objectives: The purpose of this study was to adopt and calibrate the fracture risk assessment algorithm FRAX® for the Iranian population and to provide the required guidance on how to apply it in clinical practice. Methods: The age-specific ten-year probability of major osteoporotic fractures was calculated in women with an average BMI to determine the fracture probability a...
متن کاملRBF-based surrogate model for evolutionary optimization
Many today’s engineering tasks use approximation of their expensive objective function. Surrogate models, which are frequently used for this purpose, can save significant costs by substituting some of the experimental evaluations or simulations needed to achieve an optimal or near-optimal solution. This paper presents a surrogate model based on RBF networks. In contrast to the most of the surro...
