The primary outcome was the incidence of postextubation respiratory failure and re-intubation rate within 72 h. Secondary outcomes included oxygenation, breathing frequency, subjective dyspnea, ICU and hospital length of stay, and ICU mortality at day 28.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Compared with NIV, HFNC reduced the risk of respiratory failure by 8.4%, 95% CI 6.2\u201312.8%.

In addition, the 2 groups had no significant difference in ICU and hospital length of stay. The HFNC and NIV groups had comparable hospital mortality rates. The multivariable logistic regression analysis revealed the presence of severe obesity, comorbidities, a higher severity score, and hypercapnia remained as factors associated with an increased risk of re-intubation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>\n                      Postextubation application of HFNC may prevent respiratory failure in patients who are obese.
