Pulse vs continuous dexamethasone therapy

Death or bronchopulmonary dysplasia at 36 weeks PMA · preterm infants at risk for bronchopulmonary dysplasia

Pulse may leads to higher death or bronchopulmonary dysplasia at 36 weeks' PMA compared with continuous dexamethasone therapy (low certainty).

Pulse vs continuous dexamethasone therapy

Death or abnormal neurodevelopmental outcome (various definitions) · preterm infants at risk for bronchopulmonary dysplasia

It is very uncertain whether pulse changes death or abnormal neurodevelopmental outcome (various definitions) compared with continuous dexamethasone therapy (very low certainty).

Pulmonary artery perfusion with blood vs no perfusion during cardiopulmonary bypass

Mortality within the longest · adult surgical patients with the need for cardiopulmonary bypass‐dependent heart surgery

It is very uncertain whether pulmonary artery perfusion with blood changes all‐cause mortality within longest compared with no perfusion during cardiopulmonary bypass (very low certainty).

Pulmonary artery perfusion with blood vs no perfusion during cardiopulmonary bypass

Participants with ≥ 1SAE within longest · adult surgical patients with the need for cardiopulmonary bypass‐dependent heart surgery

It is very uncertain whether pulmonary artery perfusion with blood changes participants with ≥ 1SAE within longest compared with no perfusion during cardiopulmonary bypass (very low certainty).
