  1. CI confidence interval, COPD chronic obstructive pulmonary disease, HR hazard ratio, SOFA Sequential Organ Failure Assessment
  2. aCOPD was not retained in the final model in the sensitivity analysis, with 561 patients discharged without organ failure
  3. bRefers to maximum SOFA score observed during ICU stay, entered as a continuous variable and modeled as a non-linear term
  4. cRefers to SOFA score at ICU discharge, entered as a continuous variable and modeled as a non-linear term
  5. dChange in hazard ratio estimated for one unit change in albumin level measured in g/L. Albumin was modeled as a linear term in the Cox model
