Among 629 children with ADHD screened using the Pediatric Sleep Questionnaire (PSQ), 293 had at least 8 positive responses and underwent home respiratory polygraphy; 147 had clinical features consistent with pediatric OSA and met the prespecified respiratory-polygraphy criterion of a respiratory event index (REI)\u2009\u2265\u20091 event\/hour, and 141 completed follow-up.
