  1. *Individual haplotypes were obtained from the HapMap database.
  2. #Haplotypes were composed of the following SNPs of IGF1 in listed order: rs17032648, rs12579108, rs12579077, rs35767, rs5742612, rs2288377, rs2162679, rs5742615 (SNPs in bold were investigated in this study).
  3. ‡CHB represents HapMap Chinese population, JAP represents HapMap Japanese population, and CEU represents HapMap Caucasians.
