  2. b Conventional multivariable logistic regression adjusting for age, surgical and selected comorbid conditions, Charlson Comorbidity index, hospital levels, principal diagnoses, number of acute organ dysfunction, and intensive care status.
  3. c Men and women were matched one-to-one by the propensity score and then analyzed in the logistic regression models.
  4. d Other ARF patients included those without underlying COPD or CHF.
  5. aOR, adjusted odds ratio; CHF, congestive heart failure; CI, confidence interval; COPD, chronic obstructive pulmonary disease; GEE, generalized estimating equations; INV, invasive ventilation; INV-only, use of INV as the only ventilator treatment; NIV/INV, use of both NIV and INV before or after each other; NIV, noninvasive ventilation; NIV-only, use of NIV as the only ventilator treatment.
