^*: Weight category is categorised according to recommendations by Singapore's Health Promotion Board where Overweight is defined as BMI > 90^th centile for age. Where BMI is not available, weight > 90^th centile for age is used instead; ^#: OSA severity - NA implies that polysomnography was not done for the patient; ^{^}: PEEP - Positive End Expiratory Pressure.
