* none died. Cox regression was fitted for re-hospitalization within 30, 90, and 180 days after discharge with mortality as competing event. Logistic regression was fitted for mortality within 30, 90, and 180 days after discharge. Estimates shown are hazard ratios (HR) and odds ratios (OR) with corresponding 95% confidence intervals (CI) and p-value. Model 1: unadjusted. Model 2: adjusted for age, sex, and COPD.
