Table 4 Adjusted odds ratio and CI of ventilation impairments

From: Ventilation impairment of residents around a cement plant

  Ventilation impairment Obstructive type Restrictive type
Group LEG 1      
  MEG 2.63 (1.50-4.61) 1.60 (0.72-3.65) 2.55 (1.37-4.76)
Sex Female 1      
  Male 3.30 (1.68-6.48) 4.16 (1.35-12.83) 2.26 (1.09-4.66)
Age (yrs) ≤59 1      
  60 ~ 69 2.92 (1.53-5.60) 3.20 (1.13-9.06) 2.09 (1.01-4.29)
  ≥70 7.03 (3.71-13.32) 5.74 (2.09-15.76) 4.34 (2.20-8.54)
Smoking history Never 1      
  Current/ex smoking 1.44 (0.72-2.84) 3.10 (1.10-8.66) 0.75 (0.35-1.60)
  1. Logistic regression with adjusted for all variables, CI: 95% confidence interval, MEG: more exposed group, LEG: less exposed group.
  2. Ventilation impairment, Obstructive type; FEV1/FVC <0.7, Restrictive type; FEV1/FVC ≥0.7 & FVC% predicted <80%.
