National Sleep Research Resource

The National Sleep Research Resource (NSRR) offers free web access to large collections of de-identified physiological signals and clinical data elements collected in well-characterized research cohorts and clinical trials. Using the tools provided, the researcher can search across thousands of data elements, identify those data of most relevance for given needs, explore the statistical distributions of each, and download the data as CSV files. Data include demographic, physiological, clinical, and other data types collected by each study. Physiologic signals from overnight polysomnograms (sleep studies) are available by downloading European Data Format (EDF) files. The researcher can load summary measures of standardly scored sleep data. Specific scored annotations can be accessed by downloading XML files and can be viewed offline using the EDF Viewer.

国家睡眠研究资源库（National Sleep Research Resource, NSRR）为研究者提供免费网页访问权限，可获取来自特征明确的研究队列与临床试验中采集的海量去标识化生理信号与临床数据元素集合。依托平台内置工具，研究者可检索数千个数据元素，筛选出与自身研究需求高度相关的数据，探究各数据的统计分布特征，并以逗号分隔值（CSV）文件格式下载数据。数据涵盖各研究采集的人口统计学、生理学、临床医学及其他类型数据。整夜多导睡眠图（睡眠监测）的生理信号可通过下载欧洲数据格式（European Data Format, EDF）文件获取。研究者可加载经标准化标注的睡眠数据汇总指标。特定的标注注释可通过下载可扩展标记语言（Extensible Markup Language, XML）文件获取，并可借助EDF查看器离线浏览。
