Higher number of lost teeth (per one additional lost tooth) vs Fewer lost teeth (continuous, per-tooth increment)

All-cause mortality (ACM) · Adults (any age) with a known number of remaining teeth, followed prospectively in cohort studies

Each additional lost tooth was associated with a multivariable-adjusted HR of 1.02 (95% CI 1.01 to 1.03) for all-cause mortality (11 studies, I2=89%), statistically significant; GRADE per-analysis ratings reported in Supplementary File 7 (not available in provided sources).

1-19 remaining teeth vs 20-32 remaining teeth

All-cause mortality (ACM) · Adults (any age) with a known number of remaining teeth, followed prospectively in cohort studies

In prospective cohorts, adults with 1-19 teeth had a higher cumulative incidence of all-cause mortality than adults with 20-32 teeth (RR 1.76, 95% CI 1.41 to 2.19; 8 cohort studies, I2=94%); GRADE per-analysis ratings reported in Supplementary File 7 (not available in provided sources).

Edentulous (0 remaining teeth) vs 1-32 remaining teeth

Atherosclerotic cardiovascular disease (ACVD)-related events (morbidity and mortality) · Adults (any age) with a known number of remaining teeth, followed prospectively in cohort studies

In prospective cohorts, the multivariable-adjusted HR for ACVD-related events in edentulous adults (0 teeth) vs adults with 1-32 teeth was 1.21 (95% CI 1.07 to 1.36; 5 studies, I2=35%); GRADE per-analysis ratings reported in Supplementary File 7 (not available in provided sources).

0-19 remaining teeth vs 20-32 remaining teeth

Atherosclerotic cardiovascular disease (ACVD)-related events (morbidity and mortality) · Adults (any age) with a known number of remaining teeth, followed prospectively in cohort studies

In prospective cohorts, the crude HR for ACVD-related events in adults with 0-19 teeth vs adults with 20-32 teeth was 2.27 (95% CI 1.50 to 3.43; 1 study, I2 not applicable (single study)); GRADE per-analysis ratings reported in Supplementary File 7 (not available in provided sources).

Atherosclerotic cardiovascular disease (ACVD)-related events (morbidity and mortality) · Adults (any age) with a known number of remaining teeth, followed prospectively in cohort studies

Each additional lost tooth was associated with a multivariable-adjusted HR of 1.02 (95% CI 1.01 to 1.03) for ACVD-related events (13 studies, I2=75%), statistically significant; GRADE per-analysis ratings reported in Supplementary File 7 (not available in provided sources).
