随机方法(请说明由何人用什么方法产生随机序列):

使用动态随机化最小化法将机构随机分配到干预组与对照组,选择机构内招募的高血压患者中女性比例;老年人(>=65岁)比例;基线SBP均值作为最小化因素,每个因素的权重相等。随机化过程将由独立于研究的人员进行,并在全部基线调查完成后开始。

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

Clusters were assigned to either the intervention or control group using a dynamic randomization minimization method. The minimization factors included the proportion of female hypertensive patients, the proportion of elderly patients (aged >=65 years), and the mean baseline systolic blood pressure (SBP) within each institution, with equal weight assigned to each factor. The randomization process will be conducted by personnel independent of the study and will commence only after the completion of all baseline surveys.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

盲法:

该试验为开放标签研究,参与者和干预实施者不进行盲法,但随访研究者和最终数据分析师完全独立于组别分配。

Blinding:

This was an open-label trial. Blinding was not applied to participants and intervention deliverers; however, follow-up investigators and final data analysts were completely independent of group allocation.

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:

数据采集将通过纸质问卷进行,数据采集完毕后将进行电子化录入。所有电子化数据包括电子化的调查问卷数据和实验室检测数据都将被储存于哈尔滨医科大学安全并有密码保护的服务器上;数据将长期保存于哈尔滨医科大学。所有纸质问卷以及知情同意书将被保存在哈尔滨医科大学带锁文件柜中。

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

Data will be collected using paper questionnaires, followed by electronic data entry after completion of data collection. All electronic data, including electronic questionnaire data and laboratory test data, will be stored on a secure, password-protected server at Harbin Medical University. Data will be retained long-term at Harbin Medical University. All paper questionnaires and informed consent forms will be stored in locked filing cabinets at Harbin Medical University.
