Table 2 LogVitDBP and ALP averages over time points for all subjects. Comparing subjects with any changing patterns in VitDBP (i.e., increasing, decreasing, or fluctuating) to those in the no change group, we observed that the "no change" VitDBP group showed overall smaller mean absolute differences in irregularity index than those in the changed group

  1. VitDBP was significantly related to the total ALP concentration (p = 0.039) and the absolute change in ALP (p = 0.0018). Neither ALP concentration nor ALP activity was significantly related to the change in tooth movement
