a trend towards significancep = 0.060
A significant two-way interaction between time and treatment was observed for glutamate (F 1,41 = 5.75, p = 0.021, partial η 2 = 0.123), but a post hoc paired t -test analysis only showed a trend towards significance in the ebselen group ( t (23) = −1.982, p = 0.060).
