Baseline characteristic of asthma patients and controls.

Except for a significant reduced lung function and specific antiasthmatic therapy in asthma patients there were no relevant differences between asthma and control groups. BMI = body mass index. FEV1 = forced expiratory volume in 1 second, TLC = total lung capacity, RV = residual volume, Rtot = total airway resistance Data are presented as a mean ± standard error of the mean (SEM) or n (%). P哮喘组与对照组之间无其他相关差异，仅哮喘患者存在肺功能显著降低，并接受了特异性抗哮喘治疗。本研究涉及的指标缩写及其全称如下：体重指数（body mass index, BMI）、一秒用力呼气容积（forced expiratory volume in 1 second, FEV1）、肺总量（total lung capacity, TLC）、残气量（residual volume, RV）及气道总阻力（total airway resistance, Rtot）。数据以均值±标准误（standard error of the mean, SEM）或例数（百分比）[n (%)]形式呈现。P
