Bone parameter analysis of µCT of EAP in rats. µCT analysis of BV/TV, Tb.Th, Tb.N and Tb.Sp of the ROI corresponding to Fig. 3, a 2 weeks after induction, b 4 weeks after induction and c 6 weeks after induction. ROIs are designated by green boxes (Fig. 3a–c) for the bone parameter analysis. Two-tailed Student’s t-test was used for comparisons between two groups. P-values less than 0.05 were considered significant with single asterisk, and P values less than 0.01 were considered significant with double asterisks
