The table shows the results of Cox proportional hazards regression analysis for Pi10 ⩾ 0.26 cm as predictor. Further potential predictors are shown for comparison: BMI, age, active smoking, a history of myocardial infarction, the CT-derived emphysema versus airway dominated phenotype and GOLD group D versus ABC. Significant differences (p < 0.05) are marked in bold. For all predictors, the regression coefficients (B), their standard errors (SE), p values, the derived odds ratios [exp(B)] and their 95% confidence intervals are shown.
