Comparison of hypoxemia, intubation procedure, and complications for non-invasive ventilation against high-flow nasal cannula oxygen therapy for patients with acute hypoxemic respiratory failure: a non-randomized retrospective analysis for effectiveness and safety (NIVaHIC-aHRF)

Patients included in the analysis	154	161	p-value
Sepsis-related Organ Failure Assessment score at 1	9.89 ± 2.52	10.45 ± 3.52	0.107
Sepsis-related Organ Failure Assessment score at 7	6.12 ± 1.22	6.62 ± 3.15	0.066
Ventilator-associated pneumonia	38 (25)	32 (20)	0.344
Duration of mechanical ventilation (days)	11.12 ± 3.45	11.78 ± 3.11	0.075
Length of stay in the intensive care unit (days)	14.11 ± 3.16	14.22 ± 4.12	0.791

Constant variables are reported as frequency (percentages) and continuous and ordinal data are demonstrated as mean ± standard deviation (SD)
The Fischer exact test was performed for constant data and the Mann-Whitney U-test was performed for continuous and ordinal data
A p-value of less than 0.05 was considered significant
