*Abcc6^−/− mice at 1 or 3 months of age were placed on different diets. Urine concentrations of calcium, phosphorus and magnesium were determined at 3, 4, 5 and 6 months of age.

^†Statistical significance in comparison to the Abcc6 ^−/− mice on control diet is indicated: ‡ p < 0.05; † p < 0.01 (n = 5–9).

ND = not determined.
