Values are means ± SE of n = 8–11/group. Letter a–g indicate differences from respectively labeled groups at p < 0.05 or *p < 0.01 (a = vs. SHAM, b = vs. ORX, c = vs. ORX + AN, d = vs. ORX + TE, e = vs. ORX + TE + AN, f = vs. ORX + TREN, g = vs. ORX + TREN + AN). BV/TV = Bone volume fraction, Tb. Th = Trabecular thickness, Tb.N = Trabecular number, Tb.Sp = Trabecular separation.
