Figure 1.

Change in mean body weight of molar-intact and molarless mice. Open and filled circles indicate mean body weight of molar-intact (control group) and molarless (molarless group) mice, respectively. We subjected 28 of 58 mice to the behavioral test and sacrificed them at 12 weeks old (15 molar-intact and 13 molarless). Therefore, the number of subjects was 15 each in control and molarless groups at 16, 20, and 24 weeks old. Data are presented as means ± SEM. Asterisks indicate statistically significant differences between groups (9, 10, 12 weeks old Mann–Whitney test, P < 0.05 , 16, 20, 24 weeks old Student t-test, P < 0.05).
