Question · asked by 1 review
Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement) vs usual practice: Oral hygiene measured by mean gingival scores
- Population
- Primary school children (aged 3-16 years) attending primary school in low- and middle-income countries (LMICs)
- Intervention
- Primary school-based interventions (one or more of: school health policy, oral health education, healthy school environment, access to oral health services, community involvement)
- Comparison
- usual practice
- Outcome
- Oral hygiene measured by mean gingival scores
The effect of school-based interventions on gingival scores is uncertain and not statistically significant (SMD 0.12; 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.
