Edentulous (0 remaining teeth) vs 20-32 remaining teeth: Atherosclerotic cardiovascular disease (ACVD)-related events (morbidity and mortality)
- Population
- Adults (any age) with a known number of remaining teeth, followed prospectively in cohort studies
- Intervention
- Edentulous (0 remaining teeth)
- Comparison
- 20-32 remaining teeth
- Outcome
- Atherosclerotic cardiovascular disease (ACVD)-related events (morbidity and mortality)
In prospective cohorts, edentulous adults (0 teeth) had a higher cumulative incidence of ACVD-related events than adults with 20-32 teeth (RR 2.65, 95% CI 1.77 to 3.98; 2 cohort studies, I2=60%); GRADE per-analysis ratings reported in Supplementary File 7 (not available in provided sources).

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.
