Objectives of Study: |
This research topic will design and apply personalized vacuum suction cups based on the mechanical optimization theory obtained from finite element analysis. It will combine 3D scanning of thoracic cage data, clinical functional evaluation, and other follow-up treatment outcomes to analyze clinical efficacy, focusing on the following objectives: (1) Main research purpose: To explore the objective correction effect of personalized vacuum suction cups guided by finite element mechanical analysis on the sternal depression morphology in patients with pectus excavatum. (2) Secondary research purpose: To investigate the safety (such as complication incidence rate) and potential subjective benefits (such as patient comfort and quality of life improvement) of this optimized scheme in clinical treatment; (3) Secondary research purpose: To explore the biomechanical characteristics of vacuum negative pressure suction cups during treatment when finite element analysis is applied to vacuum negative pressure suction cups. |

数据共享时间为:数据收集结束后6个月内开始共享,并持续共享5年;共享途径:数据可通过ResMan平台查询(http://www.medresman.org.cn/login.aspx),如需下载数据,可与研究者联系。 |
|
The way of sharing IPD”(include metadata and protocol, If use web-based public database, please provide the url): |
Data sharing time: Data sharing begins 6 months after the end of data collection and continues for 5 years; Sharing channels: Data can be queried through the ResMan platform (http://www.medresman.org.cn/login.aspx). If data download is required, contact the researcher. |
|
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: |
手工录入数据并整合至excel表中,在数据收集完成后,进行数据库锁定以防止进一步的数据修改,确保数据的完整性。 定期备份数据以防数据丢失,并确保在数据损坏时可以恢复。根据相关法规要求,将数据保存在安全的环境中,并确保数据的可及性和持久性。对收集的数据进行分析和处理,包括数据清理、整理和分析,以支持临床研究的目的。 |
|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Manually enter data and integrate it into Excel sheets. After data collection is completed, lock the database to prevent further data modifications and ensure data integrity. Regularly back up the data to prevent data loss and ensure recovery in case of data corruption. Store the data in a secure environment according to relevant regulations, and ensure data accessibility and durability. Analyze and process the collected data, including data cleaning, organizing, and analysis to support the purposes of clinical research. |
