Variables associated with FEV_{1}/FVC ratio in univariate analysis at a value of <0.1 were examined in the multiple linear regression analysis. Since the FEV_{1}/FVC ratio as percentage predicted is already corrected for height, age, and gender, we did not add this variable to the model. As eosinophils and abdominal circumference are correlated, we selected only one variable to prevent colinearity. We omitted OSAS because of the large proportion of missing data. |
