研究目的:

本研究旨在通过比较LMWH组与空白对照组妊娠结局的差异,探讨LMWH作为辅助药物改善RIF妇女FET结局的疗效。这项实用的试验有望提高接受FET周期的RIF妇女的妊娠结局。  

Objectives of Study:

This study aims to compare the differences in pregnancy outcomes between the LMWH group and the blank control group, and to explore the efficacy of LMWH as an auxiliary drug in improving the FET outcomes of women with RIF. This practical trial is expected to enhance the pregnancy outcomes of women with RIF who undergo FET cycles.

随机方法(请说明由何人用什么方法产生随机序列):

随机化序列将由医院临床试验研究中心的数据协调中心(Data Coordination Center ,DCC)的计算机生成。招募符合条件的参与者,按照随机化顺序按1:1的比例随机分配到试验组(LMWH+黄体支持)和空白对照组(仅黄体支持)。禁止参与者、研究人员、医生和后续工作人员影响个人对特定群体的分配。随机分配方案由DCC人员严格保密。不会透露给任何患者、工作人员或调查人员,包括首席研究员(PI)。

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

The randomized sequence will be generated by the computer at the Data Coordination Center (DCC) of the hospital's clinical trial research center. Eligible participants will be recruited and randomly assigned in a 1:1 ratio to the experimental group (LMWH + luteal support) and the placebo group (luteal support only) according to the randomized sequence. Participants, researchers, doctors, and subsequent staff are prohibited from influencing individual assignment to specific groups. The random allocation scheme will be strictly kept confidential by DCC personnel. It will not be disclosed to any patients, staff, or investigators, including the principal investigator (PI).
