CORE--SAMPLING AND DATA MANAGEMNET

抽样和数据管理核心将使用选定的数据库进行随机抽样。它将根据其中心任务承担多种职能，确保有效和有效地收集、处理和利用研究数据。它将确保一致的研究方法和跨地点的适当执行。 它还将发展研究的通信网络并为其提供服务，其中包括在线讨论公告栏和中央数据库，其中包含从调查问卷和实验室数据中得出的研究对象的所有分析价值。这个中央数据库将为研究科学家提供一个用户友好的、安全的、基于网络的界面，他们将能够输入自己的数据，查看自己的数据以及其他人产生的数据，并实时执行基本的统计分析，包括跨域的相关分析。抽样和数据管理核心将在学科招募的初始阶段向征聘和临床测试核心提供支助。浅谈采样与数据管理 CORE将负责涉及研究对象的安全问题。它还将与所有参与研究的科学家协商并提供服务，以提高研究数据分析和出版物的速度和质量。它将提供统计和流行病学分析支持，将在研究的早期阶段与所有调查人员协商，将支持研究手稿的编写，并确保使用适合研究设计和数据库的方法。它还将在发布前对所有表格进行数据核查。此外，抽样和数据管理核心将通过评估联邦医疗保险受益人登记文件和路易斯安那州选民登记文件与驾照/个人身份证文件的使用情况的代表性，来提高其流行病学程序的质量。它还将在这项研究中对自我报告的年龄进行数据验证。

The Sampling and Data Management core will conduct random sampling using the selected database. It will assume multiple functions pursuant to its central task of assuring effective and valid collection, processing, and utilization of study data. It will ensure consistent study methodology and proper execution across sites. It will also develop and service the communications network of the study, involving the online discussion bulletin board and the central database containing all of the analytic values derived from the study subjects, from both the questionnaires and laboratory data. This central database will feature a user-friendly, secure, web-based interface for study scientists, who will be able to enter their own data, view their own data as well as data generated by others, and to perform basic statistical analyses, including correlational analysis across domains, in real time. The Sampling and Data Management Core will provide support to the Recruitment and Clinical Testing Core in the initial phases of subject recruitment. The Sampling and Data Management Core will take responsibility for security issues involving the study subjects. It will also consult with and service all of the participating scientists to enhance the speed and quality of the data analyses and publications from the study. It will provide statistical and epidemiologic analytic support, will consult with all investigators in the early stages of the study, will support preparation of manuscripts from the study, and ensure that methods appropriate for the study design and database are used. It will also provide data verification of all tables prior to publication. Additionally, the Sampling and Data Management Core will enhance the quality of its epidemiologic procedures by evaluating how representative the use of the Medicare Beneficiary Enrollment file and Louisiana Voters Registration file is compared to the Drivers License/Personal Identification Card file. It will also conduct data verification of self-reported age in this study.
