  1. IGF-I insulin-like growth factor-I, N number, TBLH total body less head, BMC, bone mineral content, TB total body, aBMD areal bone mineral density, BMAD bone mineral apparent density as an estimate of volumetric bone mineral density, ns not significant
  2. Pearson's correlation coefficient was used. P < 0.05 was considered statistically significant
