Comparison on clinical characteristics of bronchiectasis patients with and without capsaicin cough hypersensitivity.

Numerical data were presented as mean ± standard deviation for normal distribution or otherwise median (interquartile range). Categorical data were expressed as number (percentage) and compared with chi-square test.PPM: potentially pathogenic microorganism.A minority of patients had dual etiologies, therefore the sum of proportion of individual etiologies was greater than 100%.Data in boldface indicated statistical significance.Comparison on clinical characteristics of bronchiectasis patients with and without capsaicin cough hypersensitivity.正态分布的数值型数据以均值±标准差（mean ± standard deviation）表示，非正态分布数据则以中位数（四分位数间距，interquartile range）表示。分类数据以例数（百分比）形式呈现，并采用卡方检验（chi-square test）进行组间比较。PPM：潜在致病微生物（potentially pathogenic microorganism）。少数患者存在双重病因，因此各病因占比之和大于100%。加粗字体的数据表示具有统计学意义。伴与不伴辣椒素（capsaicin）咳嗽高敏感性（cough hypersensitivity）的支气管扩张症（bronchiectasis）患者临床特征比较。
