Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

ElementPlanned (methods)Found (results)
PopulationChildren and adolescents. We included trials in which over 80% of included participants were 15 years old or younger, receiving oral appliances or functional orthopaedic appliances to treat obstructive sleep apnoea. Criteria for abnormal values for obstructive apnoea considered as one or more apnoea, of any length, per hour of sleep, measured by standard polysomnography. Trials including patients with a cleft lip or palate or both were excluded. There was no gender restriction.Children aged 4 to 10 years (mean 7.1 +/- 2.6), 20 male and 12 female, with apnoea index > 1 and dysgnathia; 32 randomised, 23 analysed.
InterventionAll types of oral and functional appliances used to treat obstructive sleep apnoea, compared with placebo or no treatment, including: Bimler appliance, Frankel appliance, Harvold appliance, Andresen appliance, bionator, bite block, Herbst appliance, Herren activator and Woodside activator.Personalised active oral appliance (n=19)
ComparisonPlacebo or no treatmentNo treatment (n=13)
OutcomesPrimary: Reduction to less than one episode of apnoea per hour (polysomnography). Secondary: (1) Reduction of apnoea episodes (polysomnography); (2) Reduction of upper airway resistance syndrome (UARS) and body-weight/BMI development; (3) Reduction of snoring (polysomnography); (4) Signs and symptoms of respiratory disease (mouth breathing, nasal airway resistance); (5) Signs and symptoms of atypical swallowing and speech production; (6) Daytime and nocturnal symptoms; (7) Change of mandibular length (cephalometric); (8) Sagittal maxilla-mandible relationship (cephalometric); (9) Width between cuspids and first molars (plaster models); (10) Arch perimeter (plaster models); (11) Overbite and overjet (plaster models); (12) Alteration of growth pattern; (13) Quality of life; (14) Side effects (tolerability); (15) Economic evaluation (costs); (16) Educational outcomes: cognitive function.Apnoea-hypopnoea index measured by polysomnography (n=1); Daytime symptoms: sleepiness, irritability, tiredness, school problems, morning headache, thirstiness in the morning, oral breathing and nasal stuffiness measured by questionnaire (n=1); Night-time symptoms: habitual snoring, restless sleep and nightmares measured by questionnaire (n=1)
Study designsRandomised controlled trials (RCTs); quasi-randomised trials (alternation, date of birth, record number) included and subjected to a sensitivity analysis.Quasi-randomised controlled trial (n=1)
