IFNG and attention deficit-hyperactivity disorder: Lastly, despite relatively few data, the ratios of IL-1β to IL-10, IL-13 and IFN-γ were lower in the ADHD than the control group and increased in the ADHDmed children (F(2, 8-17) = 3.5-5.5, p = 0.05-0.02, η2 = 0.29-0.54: e.g. IL-1b/IL-10, CON 0.45, sd 0.41; ADHD 0.21, sd 0.14; ADHDmed 0.72, sd 0.81).
