IL6 and attention deficit-hyperactivity disorder: Further, the same significant direct effects remained (see Figure S3), and we still obtained an indirect effect of IL‐6 at 9 years in the association between regular sleep routines at 3.5 years and probable ADHD diagnosis at 10 years (β = −.002; 95% CI = −0.003 to −0.001, p = .012); and between higher night awakening frequency at 3.5 years and probable ADHD diagnosis at 10 years (β = .002; 95% CI = 0.001 to 0.003, p = .012).
