采用计算机生成的随机数字表,将符合标准的80例受试者按1:1的比例随机分配至螺旋藻组(n=40)或安慰剂(n=40)。采用区组随机化以确保两组人数平衡。

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

Using a computer-generated random number table, 80 eligible subjects were randomly assigned in a 1:1 ratio to the spirulina group (n=40) or the placebo group (n=40). Block randomization was employed to ensure the balance of the two groups in terms of sample size.

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:

病例报告表的填写:完成的病例报告表由临床研究者填写,研究者必须在诊治受试者同时书写研究病例,保证数据纪录及时、准确、完整、规范、真实。更改时只能划线,旁注改后的数据并签名、注明日期。主要负责人审核病例报告表的纪录,并签名。

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

Fill in the case report form: The completed case report form shall be filled in by the clinical investigator. The investigator must write the study case along with the subject to ensure that the data record is timely, accurate, complete, standard and true. Changes can only be crossed, and the changed data can be signed and dated. The principal reviewed and signs the record of the case report form.
