Figure showing the Kaplan–Meier plots of the cumulative survival rates within the 28 days following the onset of acute respiratory failure in ICU in the overall population. The rate of mortality was significantly lower in patients treated with high-flow nasal cannula (HFNC) oxygen therapy alone (blue line) than in patients treated with noninvasive ventilation (NIV) as first-line therapy (green line), decreasing from 40 % (22/55) to 20 % (12/60) p = 0.0221 by log-rank test
