Table 3

Outcomes between patients with NIV success and late failure.

	NIV success,; N = 243 (84%)	Late failure of NIV,; N = 48 (16%)
Duration of NIV (median (IQR)), days	5.0 (3.5–7.7)	5.2 (3.4–9.0)	0.52
Duration of ICU stay (median (IQR)), days	6.6 (4.9–9.8)	9.5 (5.7–13.8)
Duration of hospital stay (median (IQR)), days	13.0 (8.3–19.1)	14.1 (9.7–22.7)	0.41
Hospital mortality	8 (3%)	44 (92%)

NIV = noninvasive ventilation; IQR = interquartile range; ICU = intensive care unit. for NIV success vs. late failure of NIV.
