Multiple linear regression model for a relative increase of fluorescent product growth velocity (R factor) in the real-time CBA assay in asthma patients. Presented variables are documented as independent determinants; however, they explain only 16% of the R factor variability.
| Fluorescent Product Growth Velocity (R Factor) | ||
|---|---|---|
| β (95% CI) | R2 | |
| FEV1, % | −0.18 (−0.31 to −0.04) | 0.16 |
| Wall thickness ratio (WTR), RB1 | 0.22 (0.08 to 0.36) | |
| Interleukin 6, BAL, pg/mL | 0.28 (0.14 to 0.41) | |
| Adjustment statistics | F = 2.9, p < 0.001 | |
The resulting standardized regression coefficient (β) with 95% confidence interval (95% CI) for a factor (independent variable) indicates the increase/decrease in standard deviations (SDs) of a dependent variable (R factor) when that particular factor increases by 1 SD and all other variables in the model remain unchanged. Abbreviations: RB1—the right upper lobe apical segmental bronchus; for other abbreviations, see footnote to Table 2.
