  1. Abbreviations: BMC, bone mineral content; BW, bone width; Ca, Calcium; [Ca], calcium concentration.
  2. aTo convert mg to mmol of calcium, divide by 40.
  3. bThere were no significant differences in size-adjusted bone mineral content (SA-BMC) between males and females at 3 and 12 months (P=0.22, P=0.16).
