Blood samples taken during acute stress in the TSST at week 12 showed for leucocytes no effect of group, F (1,31) = .21, p = .647, η p 2 = .007, a significant main effect of measuring point, F (3,93) = 10.53, p < .001, η p 2 = .076, and a marginally significant interaction of time point and group, F (3,93) = 2.56, p = .060, η p 2 = .076 (medium effect size).
