随机方法(请说明由何人用什么方法产生随机序列): |
由独立于本研究的统计师使用R软件(版本4.3.0)生成随机序列,设区组大小为4,按1:1比例将受试者分配至观察组或对照组。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
An independent statistician generated the randomization sequence using R software (version 4.3.0), with the seed number obtained from the National Time Service Center physical random number service (March 15, 2024). Stratification was performed by sex (male/female), age (≤50 years/>50 years), and herniation type (contained/sequestrated). Within each stratum, block randomization with randomly varying block sizes (4 or 6) was used, with an allocation ratio of 1:1. The randomization sequence was encrypted and imported into a central randomization system. The research coordinator logged into the system on the day of surgery to obtain real-time group allocation. |

本研究的去标识化个体参与者数据(De-identified Individual Participant Data, IPD)及数据分析代码将在文章发表后12个月内,存储于Figshare开放科学平台(https://figshare.com),分配永久DOI链接。数据共享内容包括:基线特征数据集、主要/次要结局测量数据集、统计分析代码(R/Syntax)。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
The de-identified individual participant data and the data analysis code from this study will be stored on the Figshare open science platform (https://figshare.com) for 12 months after the publication of the article, and a permanent DOI link will be assigned. The shared data includes baseline characteristic datasets, primary/secondary outcome measurement datasets, and statistical analysis code (R/Syntax). |

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: |
数据采集:本研究使用纸质病例报告表(CRF)模式采集患者信息。CRF依据研究方案专门设计,包含患者基线特征、术中实时记录(穿刺阶段、椎间孔成形阶段)及术后随访数据。术中关键指标(穿刺时间、透视次数)由不参与手术的巡回护士使用标准化计时器和计数器实时记录于纸质CRF,术后2小时内由研究护士转录至EDC系统,并交叉核对。EDC系统部署于医院本地服务器,配置自动验证规则(范围检查、逻辑跳转、时间序列验证)和审计追踪功能,确保数据实时质控。患者自评量表(VAS、ODI)通过EDC调查问卷功能在平板端完成,减少转录偏倚。数据管理:数据管理遵循《临床试验数据管理工作技术指南》及ALCOA+原则(可归因、清晰、同步、原始、准确、完整、一致、持久、可用)。设立专职数据管理员,制定数据管理计划(DMP),明确数据核查、质疑管理、锁定流程。关键变量(主要结局、随机化信息)100%源数据核查(SDV),一般变量10%抽查。数据库锁定前由独立统计师进行盲态数据审查,确认无异常模式后执行锁定。锁定后数据导出为SAS、CSV、R三种格式,用于统计分析和数据共享。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data collection: In this study, paper case report form (CRF) mode was used to collect patient information. The CRF was specifically designed according to the study protocol and contained patient baseline characteristics, intraoperative real-time records (puncture stage, foraminoplasty stage), and postoperative follow-up data. Critical intraoperative parameters (puncture time, fluoroscopy times) were recorded in paper CRFs in real time by circulating nurses who were not involved in the operation using standardized timers and counters, which were kept by a specially-assigned person in our study team to ensure real-time data quality control. Patient checklists (VAS, ODI) were completed via questionnaires to reduce transcriptional bias. Data management: Data management follows the Technical Guidelines for Data Management of Clinical Trials and ALCOA + principles (attributable, clear, synchronous, original, accurate, complete, consistent, durable and available). Establish a full-time data manager, develop a Data Management Plan (DMP), and clarify the data verification, query management and locking process. 100% Source Data Verification (SDV) for critical variables (primary outcome, randomization information) and 10% spot check for general variables. Blind data review was performed by an independent statistician prior to database lock and lock was performed after confirming no unusual patterns for statistical analysis and data sharing. |
