Data & Analysis Core

抽象数据和分析核心 计划项目(PP)的总体目标是减轻与肝细胞癌(HCC)相关的负担 死亡率。我们将通过加强对当代风险因素的了解来实现这一目标(例如， 代谢功能障碍的表型、生化和遗传标记)和预防策略(例如， 对与代谢(功能障碍)相关的脂肪相关的快速增长的肝癌进行化学预防、监测 肝病(MAFLD)。PP包括三个项目；两个共享资源核心、数据和分析 核心(发改委)和生物科学和生物标记物开发核心(BBDC)；以及行政核心，所有 共同的使命是阻止MAFLD-HCC的兴起。 这项计划的核心是利用和扩大我们的多元化、持续的MAFLD潜在队列- 相关的肝硬变，以及国家退伍军人事务部(VA)确定的回溯性队列 数据集。这三个项目的目标要求严格执行精心设计的议定书 协调和实施患者登记、生物检验和数据收集。此外，他们还需要 对肝硬变患者进行最佳、完整的随访，以确定参与者是否患上了肝癌。BBDC 需要支持计划和系统来跟踪注册站点之间的样本，以识别和选择 与特定项目相关的测试样本。所有三项PP研究都需要严格的先进方法 用于统计分析和信息技术。所有这些需求都将由发援会加以解决。 发援会的目标是在数据管理、协调、统计方面提供关键的专门知识和支持 以及为PP中的所有项目提供信息技术。DAC的具体目标是提供PP项目 和BDCC负责(1)管理和协调，包括执行和维护《手册》 多城市、多地点预期队列的业务(MoO)；(2)方案编制和系统支助，以 维护PP项目的中央数据库，跟踪样本，设计监控研究数据的计划，并制定 电子仪表盘，确保公私伙伴关系项目和核心项目合规并及时取得进展；(3) 编程、持续质量保证、研究设计指导和分析方面的统计专业知识 数据解释；以及(4)信息技术，以协调PP之间的数据收集工作 研究人员和合作者，并为用户开发与模拟模型交互的应用程序。 DAC成员在设计和统计分析各种不同的 研究以及与THCCC队列相关的技能、方案和人员的连续性。DAC将确保 所有项目和核心都实现了降低与肝癌相关的死亡率的总体目标。

ABSTRACT— Data and Analysis Core The Program Project (PP) overarching goal is to reduce the burden of hepatocellular carcinoma (HCC)-related mortality. We will achieve this goal by enhancing the understanding of contemporary risk factors (e.g., phenotypic, biochemical, and genetic markers of metabolic dysfunction) and preventive strategies (e.g., chemoprevention, surveillance) for rapidly increasing HCC related to metabolic (dysfunction) associated fatty liver disease (MAFLD). The PP includes three Projects; two shared resource cores, the Data and Analysis Core (DAC) and the Biospecimen and Biomarker Development Core (BBDC); and the Administrative Core, all with the shared mission of stemming the rising tide of MAFLD-HCC. Central to this PP is leveraging and expanding our multicity, ongoing prospective cohort of persons with MAFLD- related cirrhosis, as well as a retrospective cohort identified in the national Department of Veterans Affairs (VA) datasets. The aims of the three projects require rigorous implementation of well-designed protocols for coordination and implementation of patient enrollment and biospecimen and data collection. Further, they need optimal, complete follow-up of patients with cirrhosis to determine if the participants developed HCC. The BBDC requires support programs and systems to track samples between enrollment sites to identify and select samples for testing related to specific projects. All three PP studies also require rigorous advanced methods for statistical analyses and information technology. All these needs will be addressed by the DAC. The goal of the DAC is to provide critical expertise and support in data management, coordination, statistics and information technology for all projects in the PP. The Specific Aims of DAC are to provide the PP projects and BDCC with (1) Management and coordination, including implementing and maintaining a Manual of Operation (MOO) of the multicity, multisite prospective cohort; (2) Programming and systems support to maintain central databases for PP Projects, track samples, design programs to monitor study data, and develop electronic dashboards to ensure regulatory compliance and timely progress of PP Projects and Cores; (3) Statistical expertise for programming, ongoing quality assurance, study design guidance, and analysis and interpretation of data; and (4) Informatics technology to harmonize data collection efforts among PP investigators and collaborators and to develop apps for users that interface with simulation models. DAC members have extensive experience and expertise in the design and statistical analyses of variety of study as well as continuity of skills, protocols and personnel related to the THCCC cohort. DAC will ensure the all Projects and Cores achieve the overarching goal of reducing HCC related mortality.
