随机方法(请说明由何人用什么方法产生随机序列):

本项目采用区组随机化进行随机分组,先将纳入家庭中的主要烹饪者按照年龄(<45岁/≥45岁)、性别(男/女)、烹饪频率(根据中位数划分)、取暖情况(是否使用固体燃料)、社会经济地位(高/低)划分为区组,以EXCEL软件rand()函数生成随机数字对区组内研究对象进行赋值,并在各中心内将随机数字分布的前25%定为A组,25%-50%定为B组,50%-75%定为C组,后25%定为D组。受试者的随机化分组由对参试者、设计不知情的非参与人员进行。

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

Block randomization by age, sex, cooking frequency, heating solid fuel use, and SES. Random numbers were generated using Excel's RAND() function to assign values to participants within each block. Within each center, the first 25% of the random number distribution were designated as Group A, 25%-50% as Group B, 50%-75% as Group C, and the remaining 25% as Group D. The randomization process was conducted by personnel blinded to both participants and study design, who were not involved in trial implementation.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

由于干预措施可见(液化灶具和通风设施),本项目为开放(open-label)研究,仅对实验室检测和统计分析人员实施盲法,受试者身份、分组均对参与分析的统计人员保密。同时,为确保盲法效果,所有样本和数据在传送及录入阶段均采用编码处理,不得泄露分组信息;干预现场人员与数据管理人员须严格遵守相关保密规定。

Blinding:

This study was conducted as an open-label trial due to the visible nature of the interventions (LPG stoves and ventilation facilities). Blinding was maintained only for laboratory analysts and statistical personnel, with participant identities and group allocations concealed from the statisticians involved in data analysis. To ensure blinding integrity, all samples and data were coded during transfer and entry phases to prevent disclosure of group information. On-site intervention personnel and data management staff were required to strictly adhere to confidentiality protocols throughout the study.

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:

原始记录(问卷、检查报告单等)需妥善保存。问卷的数据均由研究者对参试者面对面访问得到,并由研究者填写。每个入选的参试者必须完成问卷。完成的问卷由监查员审查后交数据管理员,进行数据录入与管理工作。 1、数据的录入、数据库的建立 建立Epidata数据库,记录问卷表中所有的信息。数据库的样式将尽量与问卷相对应以方便录入的进行。为保证数值型数据的准确性,使用Epidata进行实验室数据双份录入并校对。对问卷中存在的疑问,数据管理员将填写疑问解答表(Data Rating Questionnaire,DRQ),并通过监查员向研究者发出询问,研究者应尽快解答并返回,数据管理员根据研究者的回答进行数据修改,确认与录入,必要时可以再次发出DRQ。 2、数据核查 数据的核查将分为人工核查和系统核查。人工核查是数据管理员通过检查数据的一致性、逻辑性等手段发现错误,产生DRQ。系统核查或程序性检查是指通过计算机程序的方法对CRF中的数据进行核查,包括范围,逻辑关系,一致性,方案的违背和偏离等。所产生的DRQ将交给临床监查员,由监查员交给研究者进行再次确定。有关的修改需要研究者签名并注明日期。 3、数据锁定 当满足以下条件时,即可锁定数据: (1)全部数据均已录入数据库并经过双份核对。 (2)全部疑问均已解决。 (3)分析人群已定义并做出判断。 4、数据处理 在数据锁定后,将数据库交统计分析人员按统计计划书要求进行统计分析,并撰写统计分析报告。

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

Original records (questionnaires, examination reports, etc.) must be securely archived. All questionnaire data were collected by investigators through face-to-face interviews with participants and recorded by the investigators. Each enrolled participant was required to complete the questionnaire. Completed questionnaires were reviewed by monitors before being transferred to data managers for data entry and management. 1. Data Entry and Database Establishment An EpiData database was established to record all information from the questionnaires. The database structure mirrored the questionnaire format to facilitate data entry. To ensure accuracy of numerical data, double data entry and verification were performed using EpiData. For unresolved discrepancies or ambiguities in questionnaires, data managers completed Data Query Forms (DQFs), which were forwarded to investigators via monitors for clarification. Investigators were required to promptly resolve queries and return responses. Data managers then updated, validated, and entered the data accordingly, with additional DQFs issued if necessary. 2. Data Verification Data verification included manual checks and systematic checks. Manual checks: Data managers identified errors by assessing data consistency and logical coherence, generating DQFs for unresolved issues. Systematic checks: Computerized validation programs were used to scrutinize case report form (CRF) data, including range checks, logical relationships, consistency, protocol deviations, and violations. Resulting DQFs were delivered to clinical monitors, who then relayed them to investigators for confirmation. All modifications required investigator signatures and dates. 3. Database Locking The database was locked once the following criteria were met: 1). All data were entered into the database and verified through double-entry validation. 2). All queries (DQFs) were resolved. 3). Analysis populations were defined and finalized. 4. Data Processing After database locking, the database was transferred to statisticians for statistical analysis according to the predefined statistical analysis plan (SAP), followed by preparation of the statistical analysis report.
