Univariate analysis of overall survival.

Association of histologic variant as well as nestin and periostin H-scores (alone or in combination) in chemo-naïve biopsies and chemo-treated surgical specimens with patient’s overall survival (OS) indicated. Median OS was calculated in months from the date of diagnosis for chemo-naïve and from the date of surgery for chemo-treated samples. P-value was determined by log rank test. CI: confidence interval.
Univariate analysis of overall survival.

本数据集探讨了化疗初治活检标本与化疗后手术标本中的组织学亚型、巢蛋白（nestin）及骨膜蛋白（periostin）H评分（单独使用或联合应用）与患者总生存期（OS）的关联。对于化疗初治患者，总生存期中位值以确诊日期起算的月数计算；对于化疗后手术患者，则以手术日期起算。P值通过对数秩检验（log rank test）计算得出。CI：置信区间（confidence interval）。总生存期单因素分析。
