HFNC vs continuous positive airway pressure (CPAP)

Death (before hospital discharge) or BPD (supplemental oxygen/respiratory support at 36 weeks' postmenstrual age if born < 32 weeks' gestation, or 28 days if born ≥ 32 weeks' gestation) · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in death (before hospital discharge) or BPD(supplemental… compared with continuous positive airway pressure (low certainty).

HFNC vs nasal intermittent positive pressure ventilation

BPD (supplemental oxygen/respiratory support at 36 weeks' postmenstrual age if born < 32 weeks' gestation, or 28 days if born ≥ 32 weeks' gestation) · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in BPD (supplemental oxygen/respiratory support at 36 weeks'… compared with nasal intermittent positive pressure ventilation (low certainty).

HFNC vs nasal intermittent positive pressure ventilation

Treatment failure within 72 hours of trial entry · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in treatment failure within 72 hours of trial entry compared with nasal intermittent positive pressure ventilation (moderate certainty).

HFNC vs nasal intermittent positive pressure ventilation

Mechanical ventilation within 72 hours of trial entry · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in mechanical ventilation within 72 hours of trial entry compared with nasal intermittent positive pressure ventilation (moderate certainty).

HFNC vs nasal intermittent positive pressure ventilation

Nasal trauma (during assigned treatment) · preterm infants requiring primary respiratory support

Nasal high flow probably leads to lower nasal trauma (during assigned treatment) compared with nasal intermittent positive pressure ventilation (moderate certainty).

HFNC vs continuous positive airway pressure (CPAP)

BPD (supplemental oxygen/respiratory support at 36 weeks' postmenstrual age if born < 32 weeks' gestation, or 28 days if born ≥ 32 weeks' gestation) · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in BPD (supplemental oxygen/respiratory support at 36 weeks'… compared with continuous positive airway pressure (low certainty).

HFNC vs continuous positive airway pressure (CPAP)

Treatment failure within 72 hours of trial entry · preterm infants requiring primary respiratory support

Nasal high flow probably leads to higher treatment failure within 72 hours of trial entry compared with continuous positive airway pressure (moderate certainty).

HFNC vs continuous positive airway pressure (CPAP)

Mechanical ventilation within 72 hours of trial entry · preterm infants requiring primary respiratory support

Nasal high flow showed no clear difference in mechanical ventilation within 72 hours of trial entry compared with continuous positive airway pressure (moderate certainty).

HFNC vs nasal intermittent positive pressure ventilation

Death (before hospital discharge) or BPD (supplemental oxygen/respiratory support at 36 weeks' postmenstrual age if born < 32 weeks' gestation, or 28 days if born ≥ 32 weeks' gestation) · preterm infants requiring primary respiratory support

It is very uncertain whether nasal high flow changes death (before hospital discharge) or BPD (supplemental… compared with nasal intermittent positive pressure ventilation (very low certainty).

1 finding from 1 review

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

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

Unemployment rate was not independently associated with DMFT category in the adjusted model (OR 0.99, 95% CI 0.44 to 2.23); not GRADE-rated.

Populations in countries with a lower Human Development Index (high category, HDI <0.800) vs Populations in countries with a higher Human Development Index (very high, HDI >=0.800)

Caries experience (mean DMFT) · Adults aged 19-60 years

Pooled caries experience (DMFT) was similar in very-high-HDI and high-HDI countries, and meta-regression found no significant association between national HDI and DMFT; ungraded observational evidence with very high heterogeneity.
