Vitamin D (μg/day)	7.70 ± 1.00	10.88 ± 1.91	16.31	< 0.0001	< 0.0001
Vitamin E (mg α-TE/day)	9.81 ± 3.28	14	33.42	< 0.0001	< 0.0001
Vitamin B1 (mg/day)	0.94 ± 0.20	1.30 ± 0.10	18.38	< 0.0001	< 0.0001
Vitamin B2 (mg/day)	0.70 ± 0.27	1.20	29.05	< 0.0001	< 0.0001
Vitamin C (mg/day)	63.24 ± 17.75	100	39.83	< 0.0001	< 0.0001

False discovery rate (FDR) adjustment was performed using the Benjamini-Hochberg procedure, with q < 0.05 denoting FDR-adjusted statistical significance. RAE: Retinol activity equivalents; α-TE: Alpha-tocopherol equivalents; FDR: False discovery rate.
