2. Figure 1
The mean intake of calcium in the first four weeks in the nephrocalcinosis (NC) group (NC+; solid line; mean ± 1.96 × SE) is significantly higher than in the non-NC group (NC–; dashed line; mean ± 1.96 × SE) four weeks after birth. Repeated measurement for analysis of variance was P < SE is standard error of the mean.

The mean intake of phosphorus in the first four weeks in the NC group (NC+; solid line; mean ± 1.96 × SE) is significantly higher than in the non-NC group (NC- dashed line; mean ± 1.96 × SE) four weeks after birth. Repeated measurement for analysis of variance was P < SE is standard error of the mean.
