研究目的: |
主要目的:比较不同给药时机对原发性痛经的疼痛控制效果(基于VAS评分差异)。 次要目的:评估预防性连续给药与按需给药对疼痛持续时间、药物总消耗量的影响;比较三组胃肠道不良反应及其他安全性指标的差异;探索不同给药时机对患者满意度、情绪状态及睡眠质量的影响。 |

|
Objectives of Study: |
Primary Objective: To compare the effectiveness of different medication timing strategies on pain control for primary dysmenorrhea (based on the difference in VAS scores).Secondary Objectives:1To evaluate the effect of prophylactic continuous versus on-demand medication on the duration of pain and the total amount of medication consumed.2To compare the differences in gastrointestinal adverse reactions and other safety indicators among the three groups.3To explore the impact of different medication timing strategies on patient satisfaction, emotional state, and sleep quality. |

随机方法(请说明由何人用什么方法产生随机序列): |
本研究采用分层区组随机化方法,以提高基线平衡性并降低分组可预测性。以基线回顾的上次月经周期最严重疼痛VAS评分作为分层因素,分为4–5分、6–7分和8–10分3个层级;在各层内按照预先生成的随机分配表,以1∶1∶1比例分配至3个干预组。随机序列由独立统计人员采用计算机随机数法生成。受试者完成筛查并签署知情同意书后,由研究人员按随机序列确定分组。 |

|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This study employed a stratified block randomization method to enhance baseline balance and reduce group predictability. The stratification factor was the worst pain VAS score of the last menstrual cycle at baseline review, divided into three strata: 4–5 points, 6–7 points, and 8–10 points. Within each stratum, participants were allocated to the three intervention groups in a 1:1:1 ratio according to a pre-generated random allocation schedule. The random sequence was generated by independent statisticians using a computer-generated random number method. After completing screening and signing the informed consent form, participants were assigned to groups by researchers based on the random sequence. |

The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
This research plan intends to share the raw data after the completion of the study and the publication of related papers. The anticipated start time for data sharing is within 6 months following the formal publication of the paper. The sharing method is as follows: Researchers may contact the corresponding author via email to submit a data usage application, specifying the purpose and plan for data use. Upon mutual confirmation, the research team will provide the raw data in compliance with relevant ethical guidelines and data usage agreements. |

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: |
本研究采用微信端问卷平台(问卷星)进行数据采集与管理。所有与研究相关的疼痛评分、情绪状态、睡眠质量、患者满意度、不良事件等数据,均通过标准化电子流程采集并进行实时监控与备份。受试者基线资料、痛经疼痛评分、不良事件、睡眠与主观体验等信息由患者通过微信版“问卷星”小程序每日填写;每位受试者在微信端填写问卷前需进行授权登录,唯一识别码为微信授权绑定的手机号码,确保个体信息的唯一性与一致性;为确保数据质量,问卷平台设置了字段校验、缺失警告、逻辑跳转规则,避免信息缺漏与错误。数据管理严格遵循《药物临床试验质量管理规范(GCP)》和数据保护政策,确保研究数据的完整性、保密性与可追溯性。 |

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
In this study, the WeChat questionnaire platform (Questionnaire Star) was used for data collection and management. All study-related pain scores, emotional state, sleep quality, patient satisfaction, adverse events, and other data were collected through a standardized electronic process and monitored and backed up in real time. The subject's baseline data, dysmenorrhea pain score, adverse events, sleep and subjective experience and other information are filled in by the patient every day through the WeChat version of the "Questionnaire Star" applet; Each subject needs to log in with authorization before filling out the questionnaire on the WeChat side, and the unique identification code is the mobile phone number bound to the WeChat authorization to ensure the uniqueness and consistency of individual information. To ensure data quality, the questionnaire platform has set up field verification, missing warning, and logical jump rules to avoid missing information and errors. Data management strictly adheres to Good Clinical Practice (GCP) and data protection policies to ensure the integrity, confidentiality, and traceability of research data. |
