Changes in 25(OH)D levels
| Least squares means for total 25(OH)D, 25(OH)D3, and 25(OH)D2 using mixed linear model to account for initial levelsa

a
Values are reported as means and were calculated using PROC GLM with a repeated statement.
b
P compares initial and final levels using least squares means regression.
c
Indicates significance with Pearson’s correlation.
