随机方法(请说明由何人用什么方法产生随机序列):

入组药物干预的受试者先按照年龄、BMI进行分层,再以简单随机的方将受试者按比例1:1分到对照组和实验组。筛选号:按收治患者的先后顺序编排筛选号,如S01,S02,…… 随机数字表:由电脑产生随机数字,每层筛选合格的患者将得到一个随机编号。随机编号的分配按收治患者的先后顺序进行。

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

The subjects of drug intervention were stratified according to age and BMI, and then divided into the control group and the experimental group according to a simple random ratio of 1:1. Screening number: arrange the screening number according to the order of patients, such as S01, S02 Random number table: random numbers are generated by the computer. Patients who pass the screening at each level will get a random number. The random number was assigned according to the order of patients.

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:

本研究由研究者采用CRF表进行临床研究数据的采集,并转化为电子信息管理,采用受试者日记卡进行访视间期患者安全性数据的采集和管理。 原始病历和记录作为临床试验的原始文件应完整保存。原始病历和记录由研究者负责填写和保管,每次填写前应先核对病历封面的受试者信息,字迹工整易于辨认,便于与 CRF 进行数据核对。 CRF中的数据来自于原始病历和记录、实验室检查报告单等原始文件并应与原始文件保持一致。试验中的任何观察、检查结果均应及时、正确、完整、规范、真实地的填写于CRF 中。

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

In this study, the researcher used CRF table to collect the clinical research data, and transformed it into electronic information management. The subject diary card was used to collect and manage the safety data of patients during the visit interval. The The original medical records and records as the original documents of clinical trials should be kept completely. The investigator is responsible for filling in and keeping the original medical records and records. Before filling in each time, the subject information on the cover of the medical records should be checked. The handwriting is neat and easy to identify, which is convenient for data verification with CRF. The The data in CRF comes from the original medical records, laboratory test reports and other original documents and should be consistent with the original documents. Any observation and inspection results during the test shall be timely, correctly, completely, canonically and truthfully filled in the CRF.
