OSA, obstructive sleep apnea; ADHD, attention-deficit hyperactivity disorder; OR, odds ratio; CI, confidence interval; SD, standard deviation; IQR, interquartile range. The data was analyzed by using: aUnpaired T-test, bChi-Square Test, cMann-Whitney U Test. dObesity was defined by % weight-for-height > 140. eImpact on quality of life was defined as “mild” if the OSA-18 questionnaire score <60 points, and “moderate to severe” if the score > 60 points. Bold values indicate statistical significance.
