Country-level income inequality (Gini index) vs Lower vs higher income inequality categories: Oral health-related quality of life
- Population
- people aged 60 years and older living in the community
- Intervention
- Country-level income inequality (Gini index)
- Comparison
- Lower vs higher income inequality categories
- Outcome
- Oral health-related quality of life
Older adults in countries with relative income equality (low Gini index) had markedly higher OHRQoL (91.3, 95% CI 90.0 to 92.6) than those in less equal countries; the difference by Gini index was statistically significant (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.
