TNF and attention deficit-hyperactivity disorder: All of the individual parameters that differed in a significant way between ADHD and the control group had good prediction abilities for ADHD, with an AUC greater than 0.7, specifically PDW (AUC: 0.774, 95%CI: 0.627, 0.921), IL-1β (AUC: 0.851, 95%CI: 0.729, 0.973), IL-6 (AUC: 0.988, 95%CI: 0.953, 1.023), TNF-α (AUC: 0.893, 95%CI: 0.789, 0.997), M1 profile (AUC: 0.985, 95%CI: 0.946, 1.024), proinflammatory cytokine profile (AUC: 0.761, 95%CI: 0.611, 0.911), and proinflammatory/anti-inflammatory ratio (AUC: 0.782, 95%CI: 0.638, 0.926).
