  1. N total number, IQR interquartile range, BMI body mass index
  2. Notes: The chi-square test of homogeneity was used to test for differences between categorical variables. The two-sided student’s t-test was used to test for differences between continuous variables. All variables were measured at Year 1 Visit, with the exception of pack-years, which was based on the baseline visit
  3. COPD cases were excluded if missing information necessary to code the consensus or weight-loss cachexia traits. Continuous variables (age, BMI, FEV1% predicted) are represented by median (IQR). Significant p-values are bolded
