Linear multivariate regression analysis: association between SGRQ total-score and FEV1 (% pred.) adjusted for sex, augmentation therapy and occupational dust exposure
| Variable | Unstandardized coefficient, B | Standardized coefficient, β | 95% CI | P-value |
|---|---|---|---|---|
| FEV1 (% pred.) | −0.39 | −0.41 | −0.48 to −0.30 | <0.001 |
| Sex, female | 3.50 | 0.09 | −0.04 to 7.05 | 0.053 |
| Augmentation therapy | 2.77 | 0.07 | −0.80 to 6.34 | 0.128 |
| Occupational dust exposure | 5.50 | 0.15 | 1.96 to 9.04 | 0.002 |
| Dependent variable: SGRQ total-score |
Abbreviations: CI, confidence intervals; FEV1, forced expiratory volume in 1 second; SGRQ, St George’s Respiratory Questionnaire; % pred., % of the predicted normal value.
