HFNC vs low flow nasal cannula (LFNC)

Treatment failure · respiratory support in term infants (infants ≥ 37 weeks gestational age to the end of the neonatal period (up to 1 month postnatal age))

Summary of findings table ‐ High flow nasal cannula (HFNC) may leads to lower treatment failure compared with low flow nasal cannula (LFNC) (low certainty).

High NSP coverage vs no/low NSP coverage

HCV incidence adjusted analyses number of HCV seroconversion · people who inject drugs

It is very uncertain whether high NSP coverage changes HCV incidence adjusted analyses number of HCV seroconversion compared with no/low NSP coverage (very low certainty).

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).

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

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).
