| ≥7 sick leave days due to any reason within 12 months | 1.43 (1.22–1.68) |
The subjects without current cough served as the control group (n=2720). The odds ratios (aOR) were adjusted for age, sex, body mass index, sum symptom score, depressive symptoms, family incomes and cigarette pack-years. Logistic regression analysis with backward directed stepwise process.
