Association Among Systemic Immune-Inflammation Index, Vitamin D Status and Clinical Subtypes of ADHD: A Retrospective Investigation
By Tingting Lu, Yingying Chen, Feiping Hu and 1 others.
Abstract
Background
Attention-deficit/hyperactivity disorder (ADHD) has been linked to immune dysregulation and nutritional imbalance. The systemic immune-inflammation index (SII) is a composite inflammatory marker, while serum 25-hydroxyvitamin D (25(OH)D) reflects vitamin D status. Their joint association with paediatric ADHD remains incompletely characterised.
