随机方法(请说明由何人用什么方法产生随机序列):

项目负责人使用SPSS 24.0 产生随机号,根据肥胖症受试者就诊的顺序将受试者按1:1 的比例随机分配到试验组(taVNS+生活方式指导)和对照组(非taVNS+生活方式指导)。

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

The principle investigator used SPSS 24.0 to generate the random number and the subjects were randomly assigned to the experimental group (taVNS+ lifestyle guidance) and the control group (non-taVNS + lifestyle guidance) at a ratio of 1:1 according to the order of visiting the obese subjects.

盲法:

双盲,评估人员和患者均设盲

Blinding:

Both assessor and pariticipants were blinded.

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:

1)研究者根据受试者的原始观察记录,保证将数据正确、完整、清晰、及时地载入病例报告表; 2)所有受试者资料全部从病例报告表录入EDC数据库; 3)数据库锁定; 4)数据导出、统计分析:统计分析使用SPSS或R; 5)数据备份、保存; ①研究者保存所有研究资料,包括对所有受试者的医院原始记录、所有原始的有签名的知情同意书,治疗的详细记录等;②病例报告表在按要求完成数据录入和核查后,按编号的顺序归档保存,并填有检索目录等,以备考察;③电子数据文件包括数据库、检查程序、分析程序、分析结果、编码本和说明文件等,应分类保存,并有多个备份保存于不同磁盘或记录介质上,妥善保存,防止损坏。所有原始文档按相应规定保存5年。

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

1) The investigator ensures that the data are correctly completely legibly and timely loaded onto the case report form based on the subject's original observation record. 2) All subject data were entered into the EDC database from the case report form. 3) Database locking. 4) Data export and statistical analysis using SPSS or R. 5) Data backup and preservation: (1) The investigator is responsible for saving all study data including the original hospital records of all subjects all original signed informed consent forms detailed records of treatment etc. (2) Once the case report form has been completed and verified it should be filed in the order of the number to save and fill in the search directory etc. In order to prepare for the examination the electronic data files including databases examination procedures analytical procedures analytical results codebooks and descriptions of the documents should be classified and saved. Furthermore multiple backups should be saved on different disks or recording media in order to prevent damage. In accordance with the pertinent regulations all original documents are to be retained for a period of five years.
