Independent variable | Simple regression | Multiple regression# | ||
OR (95% CI) | p-value | OR (95% CI) | p-value | |
NTM lung disease yes/no | 7.01 (2.3–21.1) | 0.0005 | 5.1 (1.5–17.0) | 0.008 |
FEV1 L | 0.25 (0.10–0.64) | 0.003 | 0.34 (0.13–0.89) | 0.028 |
OR: odds ratio; CI: confidence interval; FEV1: forced expiratory volume in one second. #: multiple logistic regression model with Aspergillus-related lung disease (serology and radiology combined) as the binary dependent variable and NTM lung disease, age and FEV1 as independent variables. Age did not contribute significantly to the model. See the Methods section for details.
