Levels and categories of serum 25[OH] vitamin D in nmol/L overall and by patient, control and their respective families are shown. The lower values represent the number of participants in each category who consumed supplemental vitamin D and the percentage of the category in each group. Based on (n = 193) available serum levels.

* Because of some missing data on serum 25[OH] vitamin D levels, percentages do not sum to 100%. Missing data were as follows:

5 from IBD.

3 from Family IBD.

3 from Control.

2 from Family Control.

** patient vs. family: p = 0.0332 (paired t test) or p = 0.0164 (for log values).
