25(OH)D levels pre- and post-aHSCT by study groups.
(A) 25(OH)D levels increased in both groups at day 30 and day 100 post-aHSCT. The increase was significantly greater in the high Vit D group at day 30; however, this significant elevation was no longer apparent at day 100 post-aHSCT; (B) The magnitude of change in 25(OH)D level at day 30 post-aHSCT was significantly higher in the vit D group, compared with the control. However, this difference was no longer apparent at day 100 post-aHSCT. *P <0.05.
