All of the individual parameters that differed in a significant way between ADHD males and the control males had good prediction abilities for ADHD in females with an AUC greater than 0.8, specifically IL-1β (AUC: 0.820, 95%CI: 0.666, 0.974), IL-6 (AUC: 0.990, 95%CI: 0.953, 1.027), TNF-α (AUC: 0.836, 95%CI: 0.688, 0.984), and M1 profile (AUC: 0.971, 95%CI: 0.908, 1.034).
