title: A retrospective study of a calcium agent (E-Ca) using data on bone mineral density obtained by DXA method.
abstract: OBJECTIVE
  We performed a retrospective analysis of a calcium hydroxide-containing calcium agent (TACHIKAWA DENKAI CALCIUM™: E-Ca) based on data of bone mineral density obtained by dual-energy X-ray absorptiometry (DXA) to clarify the relationship between bone mineral density and E-Ca intake on an empty stomach in those who regularly use E-Ca.
  
  
  RESULTS
  We found the percentage of volunteers with their age-matched (AM) values of above 100% to be 89%, and also a moderate positive correlation between AM values and the intake period of E-Ca.
  
  
  CONCLUSIONS
  Our findings demonstrate that AM values can be used as an effective indicator assessing osteogenesis by regularly administrated calcium agents which exert their effects after long-term use.
