    Adenotonsillar hypertrophy is the primary cause of obstructive sleep apnea in children.

  • 2

    Serum IgA levels are significantly higher in children with moderate-to-severe obstructive sleep apnea.

  • 3

    Logistic regression identified serum IgA and tonsillar hypertrophy as independent risk factors for OSA severity.

  • 4

    The study found that lower oxygen saturation is a protective factor against moderate-to-severe OSA.

  • 5

    A combined diagnostic model using IgA and anatomical metrics achieved an AUC of 0.852 for diagnosing OSA.
