研究目的:

本研究旨在通过随机、双盲、对照的临床试验,评估含有可产生色氨酸结合胆酸(Trp-CA)副干酪乳杆菌对超重或肥胖成人体重及代谢指标的影响,探讨其调节肠道微生态与代谢健康的潜在机制,为肥胖及代谢紊乱的营养干预提供科学依据。  

Objectives of Study:

This study aims to evaluate the effects of a probiotic supplement containing Lactobacillus paracasei producing tryptophan-conjugated bile acids (Trp-CA) on body weight and metabolic parameters in overweight or obese adults through a randomized, double-blind, controlled clinical trial. It seeks to explore the potential mechanisms underlying its regulation of gut microbiota and metabolic health, thereby providing scientific evidence for nutritional interventions targeting obesity and metabolic disorders.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用计算机生成的随机数字序列进行受试者分组,确保随机性和无偏性。具体方法如下: 使用软件:随机数字由R软件生成,保证每位受试者有相等的概率被分配到试验组或对照组。 操作流程:由独立于临床评估人员的统计人员进行随机化,确保分组过程完全保密。

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

This study employed computer-generated random number sequences for subject allocation to ensure randomization and lack of bias. The specific methodology is as follows: Software used: Random numbers were generated using R software to guarantee each subject had an equal probability of being assigned to either the experimental or control group. Procedure: Randomization was conducted by a statistician independent of the clinical evaluators to ensure complete confidentiality throughout the allocation process.

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

公开/Public

盲法:

受试者:不知晓纳入的组别; 研究人员:临床评估人员、实验检测人员及数据分析人员均不知晓分组情况; 分配人员:仅负责随机数字的独立人员掌握分组信息。

Blinding:

Subjects: Unaware of assigned group; Researchers: Clinical evaluators, laboratory technicians, and data analysts remain unaware of group assignments; Assignor: Only the independent individual responsible for generating random numbers possesses group assignment information.

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:

本研究将使用病例记录表(CRF)收集所有临床数据,并采用基于互联网的电子数据采集系统(EDC)- ResMan 平台进行数据的电子化录入、管理和存储。系统将通过逻辑核查和数据质疑等功能保障数据质量与完整性。

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

This study will collect all clinical data using case report forms (CRFs) and employ an internet-based electronic data capture (EDC) system—the ResMan platform—for electronic data entry, management, and storage. The system will ensure data quality and integrity through features such as logical checks and data queries.
