However, there was a statistically significant group × time interaction effect for total NK cells ( F (1,17) = 4.473, p = 0.049, η 2 = 0.208) and CD16− Regulatory cells ( F (1,17) = 7.755, p = 0.013, η 2 = 0.313) and the group × time interaction effect for CD16+ effector cells was close to significance ( F (1,17) = 3.647, p = 0.073, η 2 = 0.177).
