Cox regression analysis with replacement of the BODE index for the variables that compose it, without patients with neoplasm, to identify the predictors of mortality in the 9-year period
| Variables | HR (95% CI) N=110 | P-value |
|---|---|---|
|
| ||
| Male | 0.29 (0.64–2.78) | 0.428 |
| Age (years) | −0.20 (0.93–1.03) | 0.464 |
| SpO2 (%) | −0.04 (0.85–1.07) | 0.430 |
| 6MWT (m) | −0.002 (0.73–1.50) | 0.243 |
| FEV1 (%) | −0.004 (0.98–1.01) | 0.583 |
| BMI <21 kg/m2 | 1.00 (1.38–5.33) | 0.004 |
| mMRC (score) | 0.48 (0.73–1.50) | 0.794 |
| CCI | 0.24 (0.97–1.68) | 0.074 |
| Exacerbation (n) | 0.38 (1.08–1.99) | 0.013 |
Notes: All variables were included together in the Cox proportional hazard regression (sex, age, SpO2, 6MWT, BMI, mMRC, CCI, and number of exacerbations in first 3 years) without patients with neoplasm during the follow-up. Exacerbation, number of exacerbations per patient in the 3-year period.
