Changes in upright posture time and body weight variation among the three groups. (A) No statistically significant difference in upright posture time was found between the two groups of bipedal rats at 2 weeks, and the rats in the M group were observed to stand upright for a longer time than those in the T group at 1 month (P < 0.01); the differences were more apparent at 3 months (P < 0.001) and 6 months (P < 0.001). (B) All bipedal rats in both the M and T groups presented a lower ΔW than did those in the control group within 2 months, of which the M group presented a lower ΔW than did the T group. After 2 months, no statistically significant difference was identified among the three groups of rats in terms of ΔW. a, T versus M groups P > 0.05. ΔW, body weight gain since the initial observation. C, control; T, traditional; M, modified.
