随机方法(请说明由何人用什么方法产生随机序列):

本试验采用区组随机化方法。采用R4.4.3统计软件编程,给定种子数和区组长度,按1:1比例将受试对象随机分为试验组和对照组,产生膝翻修100例、髋翻修100例受试者的随机分组表。所有符合入选标准的受试者按入院顺序依次获得受试者编号,研究者根据编号查阅对应的随机分组表,确定该受试者应分配至试验组(术后24h给药)或对照组(术后6h给药)。

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

This trial adopts a block randomization method. The randomization sequence is generated using R statistical software (version 4.4.3) by specifying a seed number and block length. Eligible subjects are randomly assigned to the experimental group or the control group in a 1:1 ratio. A randomization table is generated for 100 knee revision cases and 100 hip revision cases. All eligible subjects are assigned a subject number in order of hospital admission. The investigator then consults the corresponding randomization table based on the subject number to determine whether the subject should be allocated to the experimental group (rivaroxaban initiated at 24 hours postoperatively) or the control group (rivaroxaban initiated at 6 hours postoperatively).

在研究完成后(预计2028年6月),论文发表后6个月内,基于合理请求向通讯作者获取去标识化的原始数据。若未来上传至公共数据库,将补充平台名称及网址。

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url):

De-identified individual participant data will be available upon reasonable request from the corresponding author after publication of the primary results (expected by June 2028). If uploaded to a public database, the platform name and URL will be provided.

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:

本研究采用电子数据采集系统(EDC)进行数据采集与管理。病例报告表(CRF)由研究者参照原始病历填写,监查员核查后录入EDC系统。采用双人双机独立录入,比对一致后生成数据库。数据核查包括完整性、逻辑一致性、离群值等检查。所有疑问通过疑问表解决。最终由主要研究者、数据管理员、统计师共同审核后锁定数据库。原始数据按GCP要求保存至研究结束后5年。

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

Data are collected and managed using an Electronic Data Capture (EDC) system. Case Record Forms (CRFs) are completed by investigators based on source medical records and verified by monitors. Data are entered independently by two persons using two computers, followed by consistency checks. Data verification includes completeness, logical consistency, and outlier detection. Queries are resolved via query forms. The database is locked after joint review by the principal investigator, data manager, and statistician. Source documents are retained for 5 years after study completion in accordance with GCP requirements.
