“肺结节二维与三维体积测量的观察者内重复性比较”（中国肺癌杂志, 2014, 17(4): 336-341.）文章正文338页结果部分2.1节Logistic回归分析数据有误，文中所列“结节边缘不规则及与胸膜或血管相连软件分割不满意的比率显著增高，OR（Odds Ratios）分别为1.4、1.1、1.6”，其正确结果应为“边缘不规则结节及与血管相连结节软件分割不满意的比率明显增高，似然比（odds ratios, OR）分别为4.0、 4.5”。文中的其他各部分没有受到影响。

The primer on results of logistic regression analysis in section 2.1 on page 338 contains an error. The forward primer in the article “The irregular, pleural-attached and juxtavascular nodules have signif i cantly high odds rations (OR) of unsatisf i ed segmentation as 1.4，1.1, 1.6, respectively ” should be “The irregular and juxtavascular nodules have signif i cantly high odds rations(OR) of unsatisf i ed segmentation as 4.0, 4.5, respectively ”. The other parts of the article remain unaffected. We regret this error.
