Micro-CT of osteotomy site in tibia revealed only minor effects of baicalein. The parameters measured in tibiae were bone volume/total volume (BV/TV, a), total BMD (b), cortical BMD (c), and callus BMD (d), as well as callus volume (e) and total volume (f). For callus BMD (d), ovariectomy led to reduced values, while callus volume (e) was significantly reduced at the highest baicalein concentration. ***p ≤ 0.001, **p ≤ 0.01, *p ≤ 0.05 (NON-OVX n = 9, OVX n = 9, C1 n = 9, C2 n = 9, C3 n = 10)
