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

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

ND = not determined.
