  • Note: CI = confidence interval, COPD = chronic obstructive pulmonary disease, HR = hazard ratio, Ref. = reference.

  • * Multiplicative interaction terms were formed by multiplying sex by each of the covariates in the multivariable Cox proportional hazard model for 1-year mortality. Only significant interaction terms were reported in this table.

  • Based on the patients’ neighbourhood median income.
