研究设计:

队列研究 

Study design:

Cohort study 

研究目的:

主要目的:回顾性探讨DUS测量参数(如Exp-CA PSV、吸呼气比值等)与MALS患者接受特定治疗(手术或保守治疗)后临床结局的相关性。 次要目的:基于回顾性数据中的DUS参数,构建一个初步的、可用于预测MALS患者手术治疗获益概率的预测模型。  

Objectives of Study:

Primary Objective: To retrospectively explore the correlation between DUS measurement parameters (such as Exp-CA PSV, inspiratory/expiratory ratio, etc.) and clinical outcomes in MALS patients after receiving specific treatments (surgical or conservative). Secondary Objective: Based on DUS parameters from retrospective data, to construct a preliminary predictive model that can be used to estimate the probability of benefit from surgical treatment in MALS patients.

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:

数据采集采用电子化病例报告表和电子数据采集系统。患者基本资料及影像资料通过医院电子病历系统导出,疼痛视觉模拟评分(VAS)和体重变化结果由经过培训的调查员现场录入电脑端,系统实时逻辑校验并提示缺失值,减少人工录入误差。

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

Data collection was conducted using electronic case report forms and an electronic data capture system. Patients' basic information and imaging data were exported from the hospital's electronic medical record system, while the pain visual analog scale (VAS) and weight change results were entered on-site into the computer by trained investigators. The system performed real-time logical checks and indicated missing values, reducing manual entry errors.
