Vitamin D intake is listed in International Units (conversion to μg is IU/40). Total daily calcium is listed as g/day. Vitamin D intakes were skewed and therefore both mean ± standard deviation and median values are listed. N values for each group represents original number in the groups and n values actual numbers analyzed.
Comparisons of means of groups with and without vitamin D supplements were significant; * p < 0.01, ** p < 0.05.
