Objectives of Study: |
The primary objective of the study is to evaluate the effect of low-sodium salt compared to regular salt on systolic blood pressure in CKD patients with stages G2 or G3a of disease. The secondary objectives are to assess the effects of the low-sodium salt on diastolic blood pressure and serum potassium levels. The safety outcomes include hyperkalemia and hypokalaemia. |

随机方法(请说明由何人用什么方法产生随机序列): |
按照县进行分层,每个层内使用动态随机化最小化法将参与者随机分配到干预组与对照组,选择年龄(≤35 years; ≤45 years; ≤55 years; ≤65 years; >65years)、性别(男性;女性)和基线收缩压值(<120mmHg; <140mmHg; <160mmHg; <180mmHg; ≥180mmHg)作为最小化因素,每个最小化因素的权重相等。基线数据收集后,将集中由一位提前指定并独立于本研究的生物统计师通过计算机程序来进行随机化。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
Eligible participants will be randomized to the intervention or control group with stratification by county. Within each stratum, we utilize dynamic minimization of randomization to accomplish the randomization. Dynamic minimization of randomization can ensure good balance of key characteristics. Minimisation factors will be age (<= 35 years; <= 45 years; <= 5 years; <= 65 years; >65years), sex (male; female), and baseline systolic blood pressure (<120mmHg; <140mmHg; <160mmHg; <180mmHg; ≥180mmHg). Each Minimisation factors has an equal weight. After baseline data collection, randomization will be centrally performed by a pre-specified biostatistician (independent of the study) via a computerized program. |

盲法: |
本试验属于开放标签试验,将不对参与者与干预实施员设盲,但随访调查员和最后的数据分析师是完全独立于分组情况的。在此条件下,为最大程度地减少偏倚,采用以下方法:(1)所有参与随访的调查员完全独立于研究分组,并且在进行第一次随访前都将接受标准化培训,考核通过后方可进行随访数据收集。(2)采用高钾血症事件判定委员会对高钾血症进行判定,高钾血症判定委员会完全独立于研究分组. |
|
Blinding: |
This trial is an open-label study, where participants and intervention implementers will not be blinded, but follow-up investigators and the final data analysts are fully independent of group allocation. To minimize bias under these conditions, the following measures are implemented: (1) Blinding of Follow-up Investigators: All follow-up investigators are completely independent of group assignment. They receive standardized training before the first follow-up and must pass competency assessments prior to data collection. (2) Hyperkalemia Adjudication Committee: A Hyperkalemia Adjudication Committee, independent of group allocation, is established to adjudicate hyperkalemia events. |

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: |
1.数据收集 本研究通过面对面访谈和病例记录表的方式进行数据采集。每一位参与者都要完成病例报告表的填写。完成的病例报告表由质控员进行核查。 2.数据管理 本研究所有病例报告表将采用Epidata3.1软件进行录入。录入完成后,原始纸质资料将被储存于哈尔滨医科大学公共卫生学院带锁的文件柜中;数据将长期保存于哈尔滨医科大学公共卫生学院设有密码保护的电脑中;知情同意书将被保存在哈尔滨医科大学公共卫生学院带锁文件柜中。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
1.Data collection Data in this study are collected through?face-to-face interviews and case report forms (CRFs). Each participant is required to complete a CRF. Completed CRFs are verified by quality control officers. 2.Data management All CRFs are entered using EpiData 3.1 software. After data entry, original paper documents will be stored in locked filing cabinets at the School of Public Health, Harbin Medical University; Electronic data will be securely archived in password-protected computers at the School of Public Health, Harbin Medical University for long-term preservation; Informed consent forms will be kept in locked filing cabinets at the School of Public Health, Harbin Medical University. |
