  1. Baseline mortality was considered the predicted mortality if no additional care, other than the care instituted prior to admission to the intensive care unit (ICU), was added. The univariable estimates include only the variable indicated in the model while multivariable estimates included all variables with displayed estimates in that column. All analyses accounted for non-independence of responses due to respondents completing multiple vignettes.
  2. BMI = body mass index; NSCLC = non-small cell lung carcinoma.
