From: Non-invasive ventilation versus high-flow nasal oxygen for postextubation respiratory failure in ICU: a post-hoc analysis of a randomized clinical trial

Fig. 1

Kaplan–Meier analysis of time from the onset of post-extubation respiratory failure to death according to oxygenation strategy. Mortality rates at day 28 did not significantly differ between patients treated with high-flow nasal oxygen alone (blue line) and those treated with non-invasive ventilation (red line). Mortality at day 28 was 18% (15 out of 84 patients) with NIV and 29% (18 out of 62 patients) with high-flow nasal oxygen (difference, − 11% [95% CI, − 25 to 2]; p = 0.12 using log-rank test)
