随机方法(请说明由何人用什么方法产生随机序列):

本研究为多中心(4家医院)随机对照试验,共纳入460例患者,按1:1分配至鱼精蛋白组和自然代谢组。实验人员采用以中心为分层因素的分层区组随机化,每个中心独立生成随机序列,其中一、六中心预计各纳入130例患者,四、九中心预计各纳入100例患者,区组长度主要为4(每区组内试验组和对照组各2例,顺序随机),对于总例数不能被4整除的中心(C和D),增设一个长度为2的区组(试验组和对照组各1例)。

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

This study is a multicenter (four hospitals) randomized controlled trial that included a total of 460 patients, who were assigned to the protamine group and the natural metabolism group in a 1:1 ratio. Stratified block randomization was used with centers as the stratification factor, and each center independently generated a random sequence. Centers one and six were expected to enroll 130 patients each, while centers four and nine were expected to enroll 100 patients each. The block length was mainly four (with two cases in each block, one in the experimental group and one in the control group, randomized in order). For centers (C and D) where the total number of cases was not divisible by four, an additional block with a length of two was added (one case in the experimental group and one in the control group).

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:

数据录入时由专业的心内科医生录入,建立数据备份制度,定期对电子数据库进行备份,防止数据丢失。同时,对原始CRF进行妥善保存,以备后续数据审核和查询。严格遵守数据保密原则,对患者的个人信息及研究数据进行严格保密,仅用于本研究目的。研究结束后,对数据进行匿名化处理,以保护患者隐私。

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

Data entry is conducted by professional cardiologists, and a data backup system is established to regularly back up the electronic database to prevent data loss. Meanwhile, the original CRF is properly preserved for subsequent data review and inquiry. Strict adherence to data confidentiality principles ensures that patients' personal information and research data are strictly kept confidential and used solely for the purpose of this study. Upon completion of the study, the data is anonymized to protect patient privacy.
