(A) A Group × Age (F1,51=15.3; p<0.001) but not Sex × Age (p=0.055) interaction illustrated that MS animals gained less weight over early development than CON. A Main Effect of Sex (F1,51=5.29; p=0.025) was also observed, with females weighing consistently less than males. (B) By P55, MS subjects were comparable in weight to CON subjects (no Group × Sex differences (p=0.215), with only a Main Effect of Sex (p<0.0001).
