Control group 108.5 ± 1.96
(12) 		146.25 ± 5.79
(12) 		34.79% P=1.10x10-5*
WIFI-irradiated group 94 ± 4.99
(12) 		161 ± 5.70
(12) 		71.28% P=1.77x10-6*
Values represent the mean ± S.E.M. The number of animals is shown between parentheses.
*: p < 0.05 significant.
N.B. At the beginning of the experiment, the average body weight of the irradiated group was lower than that of the control group, but this difference in body weight was not statistically significant between the 2 groups.
