About The Study: Compared with noninvasive ventilation, high-flow nasal oxygen met prespecified criteria for noninferiority for the primary outcome of endotracheal intubation or death within 7 days in 4 of the 5 patient groups with acute respiratory failure. However, the small sample sizes in some patient groups and the sensitivity of the findings to the choice of analysis model suggests the need for further study in patients with chronic obstructive pulmonary disease, immunocompromised patients, and patients with acute cardiogenic pulmonary edema.
