Country-level dental caries prevalence (Global Burden of Disease) vs Low vs high dental caries prevalence: Oral health-related quality of life
Lower country-level dental caries prevalence was associated with better OHRQoL (low-prevalence pooled mean 81.5, 95% CI 76.5 to 86.6, higher than high-prevalence countries); statistically significant (ungraded).

Studies behind the findings
None of these reviews ties its included studies to this outcome in the data here. Cochrane reviews and reviews with headline outcomes only do not list their studies yet.
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.
