If I had to guess, the SSC (Stanford Sleep Cohort) subjects probably have some of the "fullest" PSG montages. The MNC montage info page is a collection of all the signals found across the cohorts.
The folders correspond to different cohorts that contributed to the MNC project. You can find additional (limited) information in the primary MNC publication: https://pubmed.ncbi.nlm.nih.gov/30523329/
The MNC team has not shared scoring annotation files for most of the cohorts.
Your access was granted to the mesa-commercial-use dataset (e.g., nsrr download mesa-commercial-use), so make sure your NSRR gem commands are formatted for that version of the MESA data.
Thanks for using the site. I see you have access to the Sleep Heart Health Study (SHHS).
You can read about the study protocol in these links:
Subjects were chosen from existing observational studies. There were two main visits/waves in SHHS, so some subjects have two overnight sleep studies collected. The first wave was between 1995-1998 and the second wave between 2001-2003.
Thanks for using the site. I believe the STAGES device, the Amazfit Arc (https://amazfit.bg/arc.html), did not output "raw" accelerometry data, but rather data binned at 30-second or 60-second epochs (I can't recall; haven't looked at data recently). Presumably the "activeness" column is some metric of movement, i.e., higher levels mean more activity. The device (evidently) did not output estimations of sleep vs. wake epochs.
Perhaps the MESA and HCHS dataset would be more appropriate for you. These datasets do not include raw accelerometry data either, though the 30-second epoch-by-epoch data do contain sleep-wake estimates. MESA includes concurrent PSG for many subjects.
We hope to share truly "raw" accelerometry data in future cohorts.
The HomePAP dataset split night studies are the only overnight recordings with CPAP that come to mind. All the sleep scorers in HomePAP were trained polysomnologists from American Academy of Sleep Medicine (AASM) accredited sleep centers.
Thanks for using the site!
Hey - thanks for using the site. I found this description of the protocol from the STAGES contributor.
Actigraphy data collection will begin the evening of the PSG, this is critical in order to correlate the rest/activity patterns of the Actigraph device with the findings of the PSG (sleep architecture, potential sleep disorders, etc.).
To your questions: Yes, the first night of actigraphy should correspond to the overnight PSG. You should be able to align the data based on clocktime. You may need to use the STAGES annotation files to identify the sleep period start/end, as opposed to MESA where those data are available in the CSV covariate file.
Thanks for using the site.
ABC (https://sleepdata.org/datasets/abc) PSG data (staging + events) were manually scored by RPSGTs according to AASM guidelines. I agree this information is not apparent anywhere on the site or in the manual, so I made a note to add more information in the future.
Thanks for checking out the site.
The STAGES team provided some results (e.g., AHI, respiratory event durations) in this supplemental datasets: https://sleepdata.org/datasets/stages/files/original/De-identified%20Data/PSG%20SRBD%20Variables
That's probably the closest thing you'll find to "sleep disorders diagnosis from polysomnography".
This file gives some insights into what was collected at each visit, inclduing the Interim Follow-Up: https://sleepdata.org/datasets/shhs/files/documentation?f=SHHS_Documentation_of_Analytic_Database.pdf
The only thing tracked beyond SHHS2 (i.e., 2003+) were CVD outcomes and mortality status.
