随机方法(请说明由何人用什么方法产生随机序列):

采用分层区组随机分配的方法分组,将合格病例按 1:1 比例分配到试验组和对照组。随机分配操作由广东省中医院中医药临床研究中心人员采用 SAS 9.4 的 PROC PLAN,完成程序编写和随机化的操作。将随机分配结果通过网络中央随机分配系统发布。

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

A stratified block randomization method was used to group the cases. Eligible cases were allocated to the experimental group and the control group at a 1:1 ratio. The randomization was performed by staff from the Clinical Research Center for Traditional Chinese Medicine of Guangdong Provincial Hospital of Chinese Medicine using the PROC PLAN procedure in SAS 9.4 to complete the program writing and randomization. The randomization results were released through a web-based central randomization system.

盲法:

由于本研究干预的特殊性,对病人和临床操作人员将无法实施盲法。但是,我们将对检查医生、结局指标数据采集的研究人员、数据管理人员以及统计人员实施盲法。

Blinding:

Due to the particular nature of the intervention in this study it will not be possible to blind the patients and clinical operators. However we will implement blinding for the physicians conducting examinations researchers collecting outcome data data management personnel and statisticians.

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:

本研究采用Epidata软件或EDC系统进行研究数据的采集。数据管理确保临床试验数据的真实性、完整性和准确性,数据管理过程需保证临床试验数据的可溯源性。以下列出数据管理的主要流程。 13.1.数据库设计 数据管理员根据CRF采用Epidata软件或EDC系统设计数据库,经测试后发布。 13.2.数据录入 CRC负责将CRF中的数据录入数据库,数据录入采用二次录入方式,由两名CRC分别录入一遍数据,数据管理员对两个数据库进行比对,产生数据不一致清单,CRC按照清单对照CRF分别修改各自的数据库,然后再进行比对,重复以上步骤,直至两个数据库完全一致。 13.3.数据质疑管理 数据管理员依据数据核查计划(DVP)编写数据核查SAS程序对数据进行核查,产生数据质疑清单,经人工核对后,生成数据质疑表,由CRA交研究者进行答疑,答疑后的质疑表再由CRA返还给数据管理员,数据管理员据此修订数据库。

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

This study will use Epidata software or an EDC system for data collection. Data management ensures the authenticity integrity and accuracy of clinical trial data and the data management process must ensure the traceability of clinical trial data. The main processes of data management are listed below. 13.1 Database Design The data manager will design the database using Epidata software or an EDC system based on the CRF and release it after testing. 13.2 Data Entry The CRC is responsible for entering data from the CRF into the database. Data entry is performed using a double-entry method with two CRCs entering the data separately. The data manager compares the two databases to generate a list of discrepancies. The CRCs then check the CRF against the list and make corrections to their respective databases. This process is repeated until the two databases are identical. 13.3 Data Query Management The data manager writes SAS programs for data verification according to the Data Verification Plan (DVP) to generate a list of data queries. After manual verification a data query form is created and handed over to the investigator by the CRA for clarification. The clarified query form is then returned to the data manager by the CRA who revises the database accordingly.
