At 180 days post-HSCT, serum levels of 25(OH)D were
significantly reduced to 20.9 ± 10.9 ng/mL (p-value = 0.02) in
relation to the baseline values (Figure 2). Sub-optimal levels
of 25(OH)D were observed in 69% of the patients, with 18%
showing vitamin D insufficiency and 51% vitamin D deficiency.
Dietary vitamin D intake was not significantly different at this
stage in relation to the baseline values (199.4 ± 135.4 IU/day).
