1. 1Too few students met 100% of guideline to model this probability, so a lower cut-off was used.
2. 2Excludes Day 3 because no students met guideline for Vitamin C on Day 3 (maximum intake = 2.96 mg).
3. 3Too few students met guideline of 10% to model this probability, so a higher cut-off was used.
4. 4Too variable by day to combine days into a single model.
5. *p < 0.05.
6. OR = odds ratio.
