Patient demographics and baseline values of studied parameters.

Data represented as mean (SEM). * p-value designates significant statistical difference between non-exacerbating (no PE) and exacerbating patients (PE) using Student's t-test or Mann-Whitney t-test when values were not normally distributed. NR indicates normal range for cell counts. BMI normal range from Health Canada (http://www.hc-sc.gc.ca).数据以均值（标准误，Standard Error of the Mean，缩写SEM）表示。*标记的p值代表非加重组（无肺栓塞，Pulmonary Embolism，缩写PE）与加重组（肺栓塞，PE）患者间存在显著统计学差异；当数据不符合正态分布时，采用学生t检验（Student's t-test）或曼-惠特尼t检验（Mann-Whitney t-test）进行组间比较。NR代表细胞计数的正常参考范围。体质量指数（Body Mass Index，缩写BMI）的正常参考范围来源于加拿大卫生部（Health Canada，网址：http://www.hc-sc.gc.ca）。
