Fig. 3. Multivariable-adjusted mean serum 25-hydroxyvitamin D [25(OH)D] levels by dietary factors (A-H). Multivariable-adjusted mean serum 25(OH)D levels were calculated via PROC GLM after adjustment for the variables in the figure and dairy intake (≤ 2, 3-4, 5-6, ≥7/wk), fatty fish intake (≤ 1/mon, 2-3/mon, 1-2/wk, ≥3/wk), instant noodle intake (≤ 1/mon, 2-3/mon, 1-2/wk, ≥ 3/wk), sugar-sweetened beverage intake (≤ 1/mon, 2-3/mon, 1-2/wk, ≥ 3/wk), breakfast eating (≤ 3, 4-6, 7 d/wk), and vitamin D-containing supplements use (yes/no). ^*P < 0.05 and ^†P < 0.01 with the leftmost category as a reference except for B (normal category as a reference).
