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.
