Lay health worker‐ vs enhanced usual care

Clinical recovery ‐ harmful or dependent alcohol use (1 to 6 months post intervention) Defined by AUDIT score < 8 (RR > 1 denotes higher likelihood of recovery) · adult patients with alcohol dependence

It is very uncertain whether lay health worker‐led interventions changes clinical recovery ‐ harmful or dependent alcohol use (1 to 6 months… compared with enhanced usual care (very low certainty).

Primary‐level worker‐led collaborative care vs usual care

Recovery from CMD ‐ intermediate term (1 to 6 months post intervention) Recovery defined by GDS ≤ 11a; HDRS < 7b; HDRS < 8c; PHQ‐9 < 6d; PHQ‐9 < 5 or 50% reduction from baselinee (RR > 1 denotes greater likelihood of recovery) · adults with common mental disorders

Primary‐level worker‐led collaborative care may leads to higher recovery from CMD ‐ intermediate term (1 to 6 months post… compared with usual care (low certainty).

Higher national income (GNI per capita) vs Lower national income (GNI categories: middle <=$15,000 / high $15,001-25,000 / very high >$25,000)

Odds of higher caries (DMFT) category · 12-year-old children across European countries (national/regional epidemiological surveys, 2011-2022)

Higher national income was strongly associated with lower odds of poor oral health (OR 0.10, 95% CI 0.03 to 0.37; about 90% lower odds); not GRADE-rated.

Higher national income (GNI per capita) vs Lower national income (GNI categories: middle <=$15,000 / high $15,001-25,000 / very high >$25,000)

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

Mean DMFT in 12-year-olds rises as national income falls: 0.90 (very high income), 2.38 (high income), 3.30 (middle income) (Figure 2); not GRADE-rated.
