随机方法(请说明由何人用什么方法产生随机序列):

(1)影像组学特征的选取与标签的建立:根据Harrell多因素分析指南,样本量至少为自变量的10倍,但本研究的样本量明显少于变量数,因此,本研究使用高维数据回归分析LASSO回归模型来筛选用于预测模型构建的最佳影像组学特征,最终筛选出一系列影像组学特征值与它们各自的系数相乘得到每一个病人的影像组学标签值,最后使用Mann-Whitney U检验比较不同预后结局组别的影像组学标签值。 (2)危险因素的分析与模型的建立:连续变量采用均数±标准差来表示,组间比较采用t检验(正态分布)或秩和检验(非正态分布);分类变量采用百分率(%)来表示,组间比较采用卡方检验或Fisher’s确切概率法。采用多因素Logistic回归分析筛选具有统计学意义(P<0.05)的自变量来构建临床模型。 (3)模型的验证:通过绘制校准(calibration)曲线来判断预测模型的校准度,以及绘制DCA曲线来评估预测模型的临床适用性。

Randomization Procedure (please state who generates the random number sequence and by what method):

( 1 ) Selection of omics features and establishment of omics labels : According to Harrell ’ s multi-factor analysis guide, the sample size was at least 10 times of the independent variable, but the sample size in this study was significantly less than the number of variables. Therefore, this study&

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

数据管理员需在数据录入前再次核查,发现问题及时通知监察员,要求研究员作出回答:他们之间的各种疑问及解答的交换应当采用疑问表的形式,疑问表应保存备案。⑵数据管理员在进行数据录入前,要了解观察表格各项目的内容及编码情况,将编码工作过程记录于编码本保存。数据库命名应规范、易懂,易查找。并保证其正确,安全和保密。⑶数据管理员录入数据可采用二次录入或校对录入。录入过程发现问题或意外情况,应做好登记并及时报告,以使迅速处理问题,数据录入结束后应抽查部分观察表格,了解录入质量,分析并处理存在的问题。⑷数据管理员应与主要研究者一起,按病例报告表中各指标数值的范围和相互关系拟定数据范围检查和逻辑检查内容。并编写相应的计算机程序,在输入前控制错误数据输入,找出错误原因加以改正,所有错误内容及修改结果应有记录并妥善保存。标本入库使用标签机打印二维码。使用生物标本库信息管理系统,进行标本库的管理,专人负责入库登记。出现标本的丢失,先由负责入库的人查找原因,再往上追查标本采集者是否贴错标签,再逐级追查是否有遗漏。将调查结果书面汇报给课题组负责人。统计分析主要由课题组的统计专业人员分析,如果遇到有争议的统计的分析,可请课题外的统计专业人员对数据进行统计分析。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

The data administrator needs to check again before data entry, notify the Ombudsman in time of finding problems, and ask the researchers to answer : the exchange of various questions and answers between them should be in the form of question sheet, and the question sheet should be kept for the record. ( 2 ) Before data entry, the data administrator should understand the contents and encoding of each item in the observation table, and record the encoding process in the encoding book. Database naming should be standardized, easy to understand and easy to find. and ensure its correctness, security and confidentiality. ( 3 ) Data administrators can input data by secondary input or proofreading. When problems or accidents are found in the input process, it is necessary to register and report in time so as to quickly deal with the problems. After the data entry is completed, some observation forms should be selected to understand the input quality, analyze and deal with the existing problems. ( 4 ) Data administrators should work with the main researchers to develop data scope inspection and logical inspection content according to the scope and relationship of each index in the case report table. And write the corresponding computer program, before input control error data input, find out the cause of the error to be corrected, all error content and modification results should be recorded and properly saved. Specimen storage using a printer to print two-dimensional code. Use biological specimen library information management system, specimen library management, responsible for warehousing registration. The loss of specimens, first by responsible for the storage of people to find the reasons, and then go up to track specimen collectors whether wrong labels, and then step by step to track whether there are omissions. The survey results are reported in writing to the head of the research group. Statistical analysis is mainly analyzed by the statistical professionals of the research group, if there is a controversial statistical analysis
