Values are Means ± SEM of n = 6-12/group. Letters a-f indicate differences from respectively labeled groups at p ≤ 0.05 or *p ≤ 0.01 (a = vs. Intact controls, b = vs. OVX, c = vs. OVX+E₂, d = vs. OVX+HLU, e = vs. OVX+E₂ HLU, f = vs. OVX+HLU+REAMB, g = vs. OVX+E₂+HLU+REAMB), h = vs. OVX+HLU+REAMB+EX, i = vs. OVX+E2+HLU+REAMB+EX. BMC = Bone mineral content, BMD = bone mineral density.
