The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):
|
Raw data were published after 5 months of the end of the study;the public management platform for clinical trials (ResMan) is adopted and open to public inspection polling.

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:
|
由本课题组负责人实施对本项目的数据管理。
(一)病理报告表
1.定义原始数据
(1)病例报告表填写的所有原始记录的内容以及依据此表产生的电子病例报告表所记录的所有原始记录内容。
(2)化验检查及其他检查项目报告表的所有原始数据。
2.数据记录
(1)研究者填写临床试验记录要求:及时、准确、完整、规范、真实;
(2)全部病例均按方案规定,认真书写病历和填写病例报告表,所有项目均需填写,不得空项、漏项(无记录的空格划斜线);
(3)病例报告表作为原始记录,做任何更正时只能划线,旁注修改后的数据,说明理由,并与参加临床试验的医师和研究者签名并注明日期,不得涂搽,覆盖原始记录;
(4)化验单齐全并粘贴在病例报告表上,病例报告表记录的数据要与病历及原始检验报告核对无误;
(5)对显著偏高或临床可接受范围以外的数据(实验室检查项目超过正常值的20%)需加以核实,由参加临床试验的医师做必要的说明;
(6)每一位受试者观察疗程结束后,研究者应在1周内将病例报告表及病历交本单位主要研究者审核、签名。
(二)电子管理系统
1.采用临床试验公共平台管理;
2.录入前再次核查:对病例报告表的进一步检查,已经审核声明签字的病例报告表交数据管理员,数据管理员对日期、入组标准、排除标准、缺失值等进行检查,如有疑问,可填写疑问表返回监察员,由研究者对疑问表中的问题进行书面解答并签名,交回数据管理员,疑问表应妥善保管;
3.数据录入:对数据录入人员培训后进行数据录入,每一份病例报告表采用双份录入法,由两人独立完成;
4.数据的审核:逐项查对数据录入与病例报告表结果值的一致性,有不一致的地方进行更正,确保数据库的数据与病例报告表上中的结果一致;
5.数据锁定:除进行上述的数据审核外,还要由主要研究者、统计人员、数据管理员和申办者共同进一步讨论和确认研究方案中的主要内容和统计分析计划书。确认全部数据均以录入数据库,全部疑问均已解决,分析人群已定义并作出判断后锁定数据。
6.数据处理:由专业统计分析人员进行统计分析。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:
|
The person in charge of this research group shall manage the data of this project.
(1) pathological report form
1. Define the original data
(1) contents of all original records filled in the case report form and all original records recorded in the electronic case report form generated according to the form.
(2) all original data in the report form of laboratory and other inspection items.
2. Data recording
(1) researchers shall fill in the clinical trial record requirements: timely, accurate, complete, standardized and true;
(2) all cases shall be carefully written and case report forms shall be filled in according to the program, and all items shall be filled in, no blank items or missing items shall be allowed (the blank Spaces without records shall be marked with slashes);
(3) the case report form shall be regarded as the original record, and any corrections shall only be underlined, the revised data shall be annotated, the reasons shall be explained, and shall be signed and dated by the physicians and researchers participating in the clinical trial, and shall not be painted to cover the original record;
(4) the test sheet shall be complete and pasted on the case report form, and the data recorded in the case report form shall be checked with the medical record and the original test report;
(5) data that are significantly higher or beyond the clinically acceptable range (20% more than the normal value of laboratory examination items) shall be verified, and the physician participating in the clinical trial shall make necessary explanations;
(6) the investigator shall submit the case report form and medical record to the principal investigator of the unit for review and signature within 1 week after the observation course of each subject.
Electronic management system
1. The public platform management of clinical trials (ResMan) was adopted;
2. To check again before entry: case report further examination, has a report on the case of audit declaration signed data managers, data managers to date, the group criteria, exclusion criteria, such as missing value for inspection, if in doubt, can fill in doubt return to inspector table, table by researchers to the question in the question to answer in writing and signed and returned to the data administrator, doubt table should be properly kept;
3. Data entry: conducted data entry after training for data entry personnel. Double-entry method was adopted for each case report, which was completed by two people independently;
4. Data audit: check the consistency of data entry and the result value of case report table item by item, and correct any inconsistencies to ensure the consistency of data in the database and the result in the case report table;
5. Data locking: in addition to the above data audit, the principal researchers, statisticians, data managers and sponsors shall further discuss and confirm the main contents of the research plan and the statistical analysis plan.Make sure all data are entered into the database, all questions have been solved, analyze the population has been defined and make a judgment before locking the data.
6. Data processing: statistical analysis is conducted by professional statistical analysts.
