The clinical pregnancy rates were 7.1% for group 1 and 10.6% for group 2, and the difference between the groups was insignificant (p = 0.532).
t test results for differences in age distribution was significant with a t value of −3.694, and family size between the two groups was insignificant (t = −0.135).
The difference between the ultrasonic and bur groups was insignificant.
Although difference between preoperative abduction and abduction gain values in terms of degrees of Group I and Group II were significant (ANOVA, F= 43.1 p = 0.000 and F = 12 p = 0.001, respectively), the difference between postoperative values of both groups was insignificant (ANOVA, F = 1.257 p = 0.268).
The difference between postoperative values of both groups was insignificant (ANOVA, F = 0.239 p = 0.627 for abduction, F = 0.76 p = 0.388 for external rotation, F = 2.764 p = 0.106 for hand to head, F = 0.354 p = 0.555 for hand to back and F = 0.363 p = 0.555 for hand to mouth).
As in our previous studies, the levels of ApoE in APP23/het mice were decreased, but the differences in the levels of Aβ and thioflavin-S-positive plaques between both groups were insignificant.
If these values are excluded, the difference in CI between the 2 groups is insignificant.
The pair-vise difference between LD and LL-1 groups is insignificant; between LD and LD-14 is significant (p-value is 3.32E-02, χ2=4.5 on 1 df); between LL-1 and LL-14 can be considered as significant (p-value is 1.10E-01, χ2=2.6 on 1 df).
As expected, the DiD estimate of the treatment effect is neither statistically and nor economically significant; in other words, the difference in leverage ratios between treatment and control groups is insignificant for every year considered prior to the 2012 tax reform.
