干预措施:

按照传统手术方法进行治疗。无材料植入,因入组患者囊肿范围较大,充填人工骨材料十分容易感染从而影响骨的愈合,因此常规对大型颌骨囊肿刮治术后不进行充填人工材料。

干预措施代码:

Intervention:

The patients were treated according to the traditional operation method.Because of the large range of cysts in the control group, the artificial bone filling materials are easy to be infected and affect the bone healing. Therefore, artificial materials are not used after curettage of large jaw cysts.

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:

个实验过程严格执行临床试验质量管理规范,所有纸质CRF记录完整、真实、清晰、客观后将试验数据输入计算机,锁定数据后储存。病例报告表(CRF)由研究者填写,每位入选病例必须完成病例报告表。完成的病例报告表由监查员审查后,第一联移交数据管理员,进行数据录入与管理工作,第一联移交后,病例报告表的内容不再做修改。 数据管理员釆用软件编制数据录入程序,进行数据录入与管理。为保证数据准确性,应由两位数据输入员独立进行双份录入并校对。对病例报告表中存在的疑问,数据管理员将通过产生疑问解答表(QF, Query Form)向研究人员发出询问,并通过监查员联系研究人员应尽快解答并返回:数据管理员根据研究人员的回答进行数据修改、确认与录入,必要时可以再次发出QF。 在数据审核并确认建立的数据库正确后,由数据管理人员、主要研究者、统计分析人员、申办者和监查管理人员共同对数据进行审核,并完成分析人群的最后定义及判断,之后由数据管理员对数据库进行锁定。锁定后的数据库或文件一般情况下不得再做改动。

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

All paper CRF records were complete, true, clear and objective, and the test data were input into the computer and stored after locking the data. The case report form (CRF) was completed by the researchers, and each selected case must complete the case report form. After the completed case report form is reviewed by the supervisor, the first copy is handed over to the data administrator for data entry and management. After the first copy is handed over, the contents of the case report form will not be modified. The data manager uses software to compile data entry program for data entry and management. In order to ensure the accuracy of the data, two data inputters should independently input and proofread. For the questions in the case report form, the data manager will send a query to the researcher by generating a query form, and contact the investigator through the inspector. The researcher should answer and return as soon as possible: the data manager can modify, confirm and input the data according to the researcher's answer, and issue QF again if necessary. After the data is reviewed and the database is confirmed to be correct, the data management personnel, main researchers, statistical analysts, sponsors and supervision management personnel jointly review the data, and complete the final definition and judgment of the analysis population, and then the data administrator locks the database. The locked database or file should not be changed under normal circumstances.
