随机方法(请说明由何人用什么方法产生随机序列):

本试验方案采用区组随机化方法。借助SAS软件,给定种子数,产生20例(A组和B组)受试者所接受处理的随机安排,即列出流水号为01~20所对应的治疗分配(即随机编码表)。

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

This test protocol uses a block randomization method. With the SAS software, given the number of seeds, a random arrangement of 20 subjects (group A and group B) was treated, ie, the treatment assignments corresponding to the serial numbers 01 to 20 (ie, random coding tables) were listed.

盲法:

本项临床研究采用随机交叉对照试验设计。由于暴露因素的特殊性,采用单盲法,即检验者单盲。试验执行者采血后,将采血管统一编号,交由检验者检测。

Blinding:

This clinical study was designed using a randomized crossover trial. Due to the particularity of the exposure factor, the single-blind method is adopted, that is, the examiner is blind. After the test executor collects blood, the blood collection tube is uniformly numbered and tested by the examiner.

Sharing raw data on designated network platforms within 6 months of trial completion

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:

数据管理:(1)填写临床试验观察表;(2)核对临床试验观察表;(3)发疑问表;(4)建立数据库;(5)数据录入;(6)数据库核查;(7)数据备份。

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

Data management: (1) fill out the clinical trial observation table; (2) check the clinical trial observation table; (3) issue the questionnaire; (4) establish the database; (5) data entry; (6) database verification; (7) data Backup.
