Clinical parameters and radiologic findings in children with RSV LRTI.

p-Values from Mann-Whitney test or Fisher's exact test and Chi square for continuous and categorical variables, respectively: p-value 1 (training versus test); p-value 2 (training versus validation set A); p-value 3 (training versus validation set B).CPAP, continuous positive airway pressure; N/A, not applicable.针对连续变量与分类变量，分别采用对应的检验方法：连续变量采用曼-惠特尼检验（Mann-Whitney test），分类变量采用费舍尔精确检验（Fisher's exact test）与卡方检验（Chi-square test）。所得p值如下：p值1（训练集与测试集对比）；p值2（训练集与验证集A对比）；p值3（训练集与验证集B对比）。其中，CPAP即持续气道正压通气（continuous positive airway pressure）；N/A即不适用（not applicable）。
