A sneak peek into the NSRR standardized metadata for validated survey instruments

Any researchers who have tried to combine multiple datasets or validate findings in another dataset know how heterogeneity across datasets can make the process difficult or even impossible. At NSRR, we are working to address these challenges by standardizing and harmonizing important sleep measures and non-sleep covariates retrospectively. Standardization aims to reach uniformity in metadata across datasets, be it channel labels, annotations, variable definitions, sleep terminology, etc. Keep reading

Characterizing Mortality and CVD for Co-Morbid Insomnia and Sleep Apnea (COMISA) in the Sleep Heart Health Study

Overview/Abstract What is the problem being addressed? Insomnia and obstructive sleep apnea commonly co-occur (COMISA). Their co-occurrence has been associated with worse cardiometabolic and mental health. However, it remains unknown if people with COMISA are at a heightened risk of incident cardiovascular events and all-cause mortality. Keep reading

Navigating the spectral slopes of the NSRR cohorts

Nataliia Kozhemiako & Shaun Purcell We recently used NSRR data to study the so-called spectral slope of the electroencephalogram (EEG), during wake, NREM and REM sleep. This work (described in a bioRxiv pre-print, Kozhemiako et al.) points to the power of NSRR data: thousands of polysomnographic studies that can be rapidly and freely repurposed to address a broad array of research questions.

The NSRR Cohort Matrix: An easier way to explore the NSRR datasets

The NSRR is constantly developing new tools to improve its user experience. One of the newly developed applications, as inspired by the Dementias Platform, is the Cohort Matrix. The NSRR cohort matrix consists of three tabs: "Cohort Overview" tab provides summary of the key characteristics (e.g. sample size, age range, license, etc.), sleep data availability (e.g. polysomnography EDF files, actigraphy, etc.) and links back to the dataset introduction page.
