Lower unemployment rate vs Higher unemployment rate (low <=5% / medium >5-10% / high >10%)

Caries experience (mean DMFT) · 12-year-old children across European countries (national/regional epidemiological surveys, 2011-2022)

Mean DMFT tended to increase with unemployment rate (low 1.23, medium 2.08, high 2.38; ANOVA p<.05); descriptive country-level means only, not meta-analyzed or GRADE-rated.

Higher per-capita expenditure on dental health care vs Lower per-capita expenditure on dental health care (USD bands: $0-50 / $51-100 / >$100)
