Correlation of channel proteins with lung function.

Spearman correlation coefficient constants and P values were computed. Corresponding correlation strength was computed by fitting data with a linear regression function. fev1pd1a, FEV1 pre-bronchodilator % predicted (continuous); pefrprd1, PEFR post-bronchodilator % predicted; perdlco, severity classification of DLCO abnormality (continuous); fev1prd2, FEV1 post-bronchodilator % predicted (continuous); sf12pcs, SF12 physical component score; fev6prd1, FEV6 pre-bronchodilator % predicted; fev1prd2, FEV1 post-bronchodilator % predicted (continuous); fvcprd2, FVC post-bronchodilator % predicted. Additional expanded abbreviations can be found in Table 1. Spearman coefficients (between −1 and +1) were calculated using Origin Pro 8.5.Correlation of channel proteins with lung function.已计算斯皮尔曼相关系数（Spearman correlation coefficient）常数与P值；通过线性回归函数拟合数据，计算得到对应的相关强度。各变量释义如下：fev1pd1a：支气管舒张前一秒用力呼气容积（FEV1）预测百分比（连续型变量）；pefrprd1：支气管舒张后峰流速（PEFR）预测百分比；perdlco：一氧化碳弥散量（DLCO）异常严重程度分级（连续型变量）；fev1prd2：支气管舒张后一秒用力呼气容积（FEV1）预测百分比（连续型变量）；sf12pcs：SF-12躯体健康成分得分；fev6prd1：支气管舒张前六秒用力呼气容积（FEV6）预测百分比；fev1prd2：支气管舒张后一秒用力呼气容积（FEV1）预测百分比（连续型变量）；fvcprd2：支气管舒张后用力肺活量（FVC）预测百分比。其余缩写的完整释义可参见表1。斯皮尔曼相关系数取值范围为-1至+1，本研究采用Origin Pro 8.5软件进行计算。本研究探讨通道蛋白与肺功能的相关性。
