  1. aValues are means ± s.d.
  2. Values are significantly different between week 0 and week 12 within the group; P<0.05.
  3. dValues are significantly different between control and vitamin B6 supplement groups at week 12; P<0.05.
  4. eValues are significantly different between control and vitamin B6 supplement groups between week 12 and week 0 (Δ(week 12−week 0)); P<0.05.
