Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Lung Function indices were performed in peking university third hospital | Repeated-measure study was conducted from November,2014 to January,2016,lung function was measured by every four months | Lung Function indices including FEV1(ml), FVC(ml),the ratio of FEV1/FVC et, al.. When we perform data analysis,these parameters will be expressed as the percentage of the predicted values based on the subject-specific sex, age,height and weight. |
