  1. a P < 0.05, values of BIS were compared between the group 1 < yr. ≤ 5 and the group 1 < yr. ≤ 2 at the same time point
  2. *P < 0.01, BIS values with superscript * compared with BIS values at 0 s time point
  3. c P < 0.05, BIS values with superscript c compared with BIS values at the other time point of group 1 < yr. ≤ 5
  4. d P < 0.05, BIS values with superscript d compared with BIS values at the other time point of group 1 < yr. ≤ 5
  5. e P < 0.05, BIS values with superscript e compared with BIS values at the other time point of group 5 < yr. ≤ 12
  6. f P < 0.05, BIS values with superscript d compared with BIS values at the other time point of group 5 < yr. ≤ 12
