Contribution of D genotype to cessation of smoking in logistic regression analysis
| Independent factor | χ2 | p value | Odds ratio | 95% CI |
|---|---|---|---|---|
| CI=confidence interval; LAA=low attenuation area score; CC=lifelong cigarette consumption; FEV1.0=forced expiratory volume in 1 second. | ||||
| *p<0.05, **p<0.01. | ||||
| Odds ratio and 95% CI correspond to having genotype D, aging every 10 years, 10 pack years increase in CC, one point increase in LAA scores, or 10% increase in %FEV1.0. | ||||
