Prognostic factors for all-cause mortality in the untreated stationary group of 93 patients
| Univariate analysis | Multivariate analysis | |||
| HR (95% CI) | p-value | HR (95% CI) | p-value | |
| Age years | 1.097 (1.031–1.167) | 0.003 | 1.094 (1.024–1.167) | 0.007 |
| Male | 2.135 (0.737–6.181) | 0.162 | ||
| BMI kg·m−2 | 0.927 (0.797–1.077) | 0.321 | ||
| Smoker | 1.946 (0.662–5.715) | 0.226 | ||
| Presence of comorbidity# | 1.347 (0.451–4.023) | 0.594 | ||
| Positive sputum AFB smear | 1.416 (0.483–4.151) | 0.526 | ||
| Spontaneous sputum conversion | 0.626 (0.217–1.806) | 0.386 | ||
| Causative organism | 0.130 | |||
| Mycobacterium avium | 1 | |||
| Mycobacterium intracellulare | 2.164 (0.797–5.876) | |||
| Radiological type: fibrocavitary | 5.356 (1.833–15.652) | 0.002 | 3.700 (1.225–11.174) | 0.020 |
| Involved lobes n≥4 | 1.297 (0.283–5.942) | 0.738 | ||
| FVC % pred <80% | 4.418 (1.409–13.849) | 0.011 | 3.325 (1.029–10.743) | 0.045 |
HR: hazard ratio; BMI: body mass index; AFB: acid-fast bacilli; FVC: forced vital capacity. #: bronchiectasis was not included in the comorbidities because nonfibrocavitary type (mostly nodular bronchiectatic type) significantly overlapped with the presence of bronchiectasis. p<0.05 was considered significant.
