Reference Intervals for 24-Hour Urinary Calcium Excretion and Its Association With Bone Metabolism: A Multicenter Study

1

The study analyzed 24-hour urinary calcium excretion (UCaE) in 1239 participants across 9 hospitals in China.
2

Median 24-hour UCaE was 2.27 mmol, with variations observed between genders and age groups.
3

In men, UCaE was positively associated with 25(OH)D and PTH, while women showed different associations.
4

The prevalence of hypercalciuria was 11.6%, significantly varying by age and region.
5

This research established reference intervals for UCaE in the Chinese population, aiding in clinical decision-making.
