Figure 6 Animal weight and changes of mid-palatal suture response to the expansion force (n=6). ( A ) Changes of body weight during experimental period (two-way analysis of variance). ( B ) Width of the mid-palatal suture (one-way analysis of variance). ( C ) Bone volume of the mid-palatal suture (one-way analysis of variance). The columns represent the means. Error bars represent standard deviations. *P < 0.05, **P < 0.01, ***P < 0.001.
