Mediation of calcium-to-phosphorus ratio in the association between kidney stones and bone mineral density in the femoral neck: a cross-sectional study based on the National Health and Nutrition Examination Survey (NHANES)
This cross-sectional NHANES study reveals that kidney stones are independently associated with reduced femoral neck bone mineral density, a relationship partially mediated by an altered calcium-to-phosphorus ratio, particularly among younger individuals and those without chronic kidney disease.
