Question · asked by 1 review
Cleft lip and/or palate (CL/P) vs Healthy controls without cleft: Clinical attachment level (CAL)
- Population
- Individuals assessed for periodontal health (mainly children and adolescents, age >2 years)
- Intervention
- Cleft lip and/or palate (CL/P)
- Comparison
- Healthy controls without cleft
- Outcome
- Clinical attachment level (CAL)
Clinical attachment level loss is greater in persons with orofacial cleft than in healthy controls (p<0.00001), but no pooled effect size was reported (ungraded).

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.
