BIOSTATISTICS

生物统计学核心将继续作为所有相关项目和核心的资源和合作者， 到这个项目。生物统计核心人员负责监督数据采集， 实施所有用于数据输入和数据管理任务的软件，并培训 合适的人员。他们还负责与调查人员及其工作人员合作， 监测数据采集过程，以确定潜在的问题来源并提出修改建议。 生物统计学核心将在提案中概述的所有跨项目数据分析中发挥主导作用。 具体而言，生物统计学核心将： 1.就所有项目的设计提供咨询，并在应用适当的统计和 方法技术。 2.协作进行所有核心和项目的数据分析和报告准备。 3.合作设计所有要使用的表格。 4.继续支持数据输入和数据管理程序，以实现具有成本效益的计算机 使用. 5.方便所有研究者访问核心收集的数据。 6.开发、应用和实施适当的统计数据分析技术， 已经收集的横截面和纵向数据。

The Biostatistics Core will continue to serve as a resource and collaborator for all projects and cores related to this program project. The Biostatistics Core personnel are responsible for overseeing data acquisition, for the implementation of all software for data entry and data management tasks, and for training the appropriate personnel. They are also responsible for collaborating with investigators and their staff in monitoring the data acquisition process to identify potential sources of problems and recommend changes. The Biostatistics Core will take a lead in all of the cross-project data analyses outlined in the proposals. Specifically the Biostatistics Core will: 1. Consult on the design of all projects and consult in the application of appropriate statistical and methodological techniques. 2. Collaborate in data analysis and report preparation for all cores and projects. 3. Collaborate in the design of all forms to be used. 4. Continue to support data entry and data management procedures to achieve cost-effective computer use. 5. Facilitate access by all investigators to data collected by the cores. 6. Develop, apply, and implement appropriate statistical data analysis techniques for combining the cross-sectional and longitudinal data that have been gathered.
