Question · asked by 1 review
Cervical pull headgear vs Minor interceptive procedures (control): Amount of crowding (lower incisor crowding) at 10 weeks
- Population
- Children or adolescents (aged 16 years old or under) receiving orthodontic treatment to prevent or correct crowded teeth
- Intervention
- Cervical pull headgear
- Comparison
- Minor interceptive procedures (control)
- Outcome
- Amount of crowding (lower incisor crowding) at 10 weeks
It is very uncertain whether cervical pull headgear changes amount of crowding (lower incisor crowding) at 2 years compared with minor interceptive procedures (control) (very low certainty).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
