Relationships Between Serum and Urine Phosphorus With All-Cause and Cardiovascular Mortality: The Osteoporotic Fractures in Men (MrOS) Study

In community-living older men, higher serum phosphorus concentrations are associated with all-cause and CVD death. In contrast, urine phosphorus-creatinine ratio and FEPi are not. These findings do not support using urine phosphorus-creatinine ratio or FEPi as adjuvant measures to predict risk of mortality or CVD in the general population.
