结局指标
主要结局
Lung Function indices were performed in peking university third hospital
时间窗: 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.
次要结局
- Inflammation related biomarkers were measured by flow cytometry(Repeated-measure study was conducted from November,2014 to January,2016,biomarkers were measured by every four months)
