Fig. 1. Change in bone mineral density at three skeletal sites with estrogen replacement in postmenopausal women, both with and without supplemental calcium. (Redrawn from the meta-analysis of Nieves et al. [17]; copyright Robert P Heaney, 2000. Used with permission.)
Fig. 2. Bone mineral density change on low dose estrogen regimens reported from five studies [18–22]. The bottom two trials used neither supplemental calcium nor vitamin D; the third and fourth trials up used calcium only, and the top trial used both supplemental calcium and vitamin D.
