项目摘要
Project Summary – Core C
The principal objective of the Data Management and Analysis Core (Core C) is to provide project investigators
a centralized resource for quantitative expertise. Statistical and methodological issues will be addressed at all
stages: from the initial design of laboratory assays and observational studies to the maintenance of data quality,
to the analysis of complex data. In support of this objective, Specific Aims of Core C are: Aim 1. Collaborate
with project investigators to align study design and analysis with research questions. Core C will assist
researchers at the design stage by: formulating biological, immunological, epidemiological, and sociological
questions as testable statistical hypotheses; devising efficient study designs and matching these with appropriate
statistical models; determining sample sizes necessary to ensure high power while controlling Type I error.
Survey development will utilize appropriate methods (e.g., cognitive interviewing or pilot testing) to ensure that
they are psychometrically appropriate. Core personnel will ensure that: the chosen designs and surveys avoid
biases and decrease measurement errors; the selected primary outcome measures will answer specific research
questions; and the statistical analysis plans will use data to answer the research questions under realistic and
transparent assumptions. Aim 2. Provide services and support for data collection and management to
ensure: integrity, security and accessibility; processing and quality control; sharing across projects;
and creating a centralized repository of all survey instruments, analysis procedures and results. To
promote data integration across projects, Core C will create a centralized repository of all data that will be secure
and accessible to investigators. Quantitative data will be cleaned, merged and de-identified. Missing and outlying
data reports will be provided to the investigators. Developed surveys will be content validated and further
validated by psychometric analyses as appropriate. Qualitative data will follow a rigorous transcription and coding
process. To ensure high data integrity and availability for statistical modeling, Core C will implement rigorous
quality control and processing procedures, using approaches such as normalization, filtering, and visualization.
Aim 3. Provide services and support for data analysis and interpretation phases of all projects. Core C
services will include: (i) formal hypothesis tests for laboratory, epidemiological, and qualitative data that ensure
strong conclusions, (ii) exploratory analyses that lead to new or refined hypotheses, (iii) statistical modeling and
sensitivity analyses of complex data, and (iv) visual displays that clarify conclusions. In accordance with critical
principles of rigor and reproducibility in science, Core C biostatisticians will work closely with investigators to
develop comprehensive analysis plans that distinguish between formal testing and exploratory analyses.
Qualitative data (e.g., cognitive interviews) will be analyzed following a standardized coding process.
项目摘要-核心C
数据管理和分析核心(核心C)的主要目标是为项目调查人员提供
一个集中的定量专业知识资源。统计和方法问题将得到解决
阶段:从实验室分析和观察性研究的初始设计到数据质量的维护,
复杂数据的分析。为了支持这一目标,核心C的具体目标是:目标1。合作
与项目研究者合作,使研究设计和分析与研究问题保持一致。核心C将协助
研究人员在设计阶段:制定生物学,免疫学,流行病学和社会学
问题作为可检验的统计假设;设计有效的研究设计,并将其与适当的
统计模型;确定必要的样本量,以确保高功率,同时控制I类错误。
调查的制定将利用适当的方法(例如,认知访谈或试点测试),以确保
它们在心理测量上是合适的。核心人员将确保:选定的设计和调查避免
偏差和减少测量误差;选定的主要结果指标将回答具体的研究
问题;统计分析计划将在现实和
透明的假设。目标2.为数据收集和管理提供服务和支持,
确保:完整性、安全性和可访问性;处理和质量控制;跨项目共享;
并建立一个所有调查工具、分析程序和结果的中央储存库。到
促进跨项目的数据集成,Core C将创建一个集中的数据存储库,
调查人员可以接触到。量化数据将被清理、合并和去识别化。失踪和边远地区
将向研究者提供数据报告。制定的调查将进行内容验证,并进一步
适当时通过心理测量分析进行验证。定性数据将遵循严格的转录和编码
过程为了确保统计建模的高数据完整性和可用性,Core C将实施严格的
质量控制和处理程序,使用标准化,过滤和可视化等方法。
目标3.为所有项目的数据分析和解释阶段提供服务和支持。芯C
服务将包括:(i)对实验室、流行病学和定性数据进行正式假设检验,
强有力的结论,(ii)探索性分析,导致新的或完善的假设,(iii)统计建模和
复杂数据的敏感性分析,以及(iv)澄清结论的视觉显示。根据批判
根据科学的严谨性和可重复性原则,核心C生物统计学家将与研究者密切合作,
制定全面的分析计划,区分正式测试和探索性分析。
定性数据(例如,认知访谈)将按照标准化编码过程进行分析。
