Multivariate analysis using logistic model for EGFR mutation testing (PPS).

OR: odds ratio; CI: confidence intervalFor patients who provided both histology and cytology samples, test results from histology samples were used.The significance level for variable selection was 0.01.NX in regional lymph nodes were excluded from the analysis.The number of patients used for this analysis was 725.Multivariate analysis using logistic model for EGFR mutation testing (PPS).OR：比值比（odds ratio）；CI：置信区间（confidence interval）。对于同时提供组织学（histology）样本与细胞学（cytology）样本的患者，将采用其组织学样本的检测结果。变量筛选的显著性水平为0.01。区域淋巴结内的NX病例被排除在本次分析之外。本次分析纳入的患者例数为725例。针对表皮生长因子受体（EGFR）突变检测，采用logistic回归模型开展多因素分析（PPS）。
