Exclusion criteria: |
1. Patients with severe hepatic or renal diseases, immunodeficiencies, severe or infectious diseases, type I diabetes, or complications such as malignant hypertension, malignant tumors, hyperthyroidism, hypothyroidism, or electrolyte disturbances; 2. Patients following special diets (e.g., for celiac disease, type I diabetes) or those who have changed their dietary patterns within 12 weeks before the start of the study; 3.

Use of omega-3 polyunsaturated fatty acid supplements or medications that may affect lipid metabolism and influence study outcomes. (Information on medication use is collected during the initial screening visit as part of a medication questionnaire. This open-ended question requires participants to provide details of all prescription and over-the-counter medications, as well as any oral supplements they are taking, including names and duration of use from start to discontinuation. Omega-3 fatty acid supplements are defined as fish oil, omega-3 fatty acids, PUFAs, DHA, EPA, or ALA. Self-reported information on omega-3 fatty acid supplementation is recorded during the initial screening visit.); 7. Individuals with an allergy to eggs. |

随机方法(请说明由何人用什么方法产生随机序列): |
随机序列由独立于试验实施与数据评估的第三方统计师(石佳璇,北京大学公共卫生学院) 采用简单随机化方法生成,通过R 4.3.1 统计软件的 sample() 函数实现受试者按 1:1:1 比例分配至三组(试验组:ω-3 多不饱和脂肪酸强化鸡蛋组;对照 1 组:普通鸡蛋组;对照 2 组:无鸡蛋干预组)。随机分配表经加密密封后存档于研究数据管理中心,全程与三盲流程隔离,揭盲前无相关人员接触分组信息。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
The random sequence was generated by an independent statistician (Jiaxuan Shi, Peking University School of Public Health) who was not involved in trial conduct or outcome assessment. Using the simple randomization method, participants were allocated in a 1:1:1 ratio to one of three groups (intervention group: ω-3 polyunsaturated fatty acid-fortified egg group; control group 1: regular egg group; control group 2: no egg intervention group) via the sample() function in R software (version 4.3.1). The resulting allocation table was encrypted, sealed, and archived at the research data management center. It remained fully isolated from the triple-blind procedure, with no personnel accessing the group assignment information prior to unblinding. |

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: |
本研究采用三盲设计,施盲对象包括受试者、干预措施执行者、结局指标评估者与数据分析师。所有参与人员全程仅知晓受试者的唯一识别代码,不了解分组对应的干预类型;随机分配表由第三方统计师加密保管,直至试验结束、数据锁定后统一揭盲。 |
|
Blinding: |
A triple-blind design was adopted in this study, and the blinded subjects included participants, intervention administrators, outcome assessors, and data analysts. Throughout the entire trial, all involved personnel were only informed of the unique identification codes of the participants and were unaware of the intervention types corresponding to each group. The random allocation table was encrypted and stored by an independent third-party biostatistician, and centralized unblinding was performed only after the trial was completed and the data were locked. |

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: |
“采用纸质或电子版 CRF 采集数据,CRF 内容涵盖受试者基线特征、干预措施执行情况、结局指标检测结果、不良事件记录等模块,所有数据填写需由经培训的研究人员完成,确保真实、准确、完整”。 ‘计划采用标准化 EDC 系统进行数据采集与管理,具体系统选型将在试验启动前确定’” |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data were collected using paper-based or electronic Case Report Forms (CRFs). The content of CRFs covered modules including participants’ baseline characteristics, intervention implementation status, outcome indicator test results, and adverse event records. All data entries were completed by trained researchers to ensure the authenticity, accuracy, and completeness of the data. A standardized Electronic Data Capture (EDC) system was planned for data collection and management, and the specific system selection would be finalized prior to the trial initiation. |
