Hey - thanks for checking out the resource. Unfortunately, I don't think you will find any datasets on our site that meet these criteria. Many of the studies/trials routinely included scorer reliability exercises, but these were done strictly for internal QA purposes.
Hello - thanks for your interest in the resource!
The SHHS dataset is available for both noncommercial and commercial use. We look forward to reviewing your data request. Please let us know if you have any other questions along the way.
Can you provide more information and/or screenshots about what you are trying to do?
I logged in and went to this URL - https://sleepdata.org/datasets/shhs/files/polysomnography/edfs/shhs2
I can download the EDFs from here. I can also Preview Online and see the signals drawn in my web browser. The files appear intact.
Hi guofan - you can find many AHI variables in the SHHS dataset here - https://sleepdata.org/datasets/shhs/variables?search=ahi (choose the best definition for your analysis)
These AHI variables exist in the datasets here - https://sleepdata.org/datasets/shhs/files/datasets
This isn't something I have ever seen annotated or derived from datasets like ours. Sorry!
You could pull an AHI variable (using your preferred definition) from the SHHS dataset and use this as a stand-in for sleep apnea diagnostic criteria (e.g. 5-15 mild, >15 moderate, >30 severe). Here's a search to some SHHS AHI variables: https://sleepdata.org/datasets/shhs/variables?search=ahi_
These were research sleep studies, so we don't have reports/diagnoses, per se.
Thanks for checking out the NSRR. Just curious, is it still slow if you try to manually download a file through your web browser, e.g. from here https://sleepdata.org/datasets/shhs/files/polysomnography/edfs/shhs1 ?
Hi - thanks for checking out the site. I think it will be possible to generate a supplemental dataset to meet your needs. I responded to the email you sent to email@example.com and I think we can sort out the details there.
No, there isn't a variable like that. These were all research studies, so neither the patient nor their sleep study were judged/assessed by a health professional.
Unfortunately I don't have any grand explanations to report. My colleague looked at the source data from some of your examples and the supine TST appeared to match your findings (i.e. differed from the CSV dataset as well). I would go with your findings in this case since that is what the raw signal is telling you.
It's hard to explain things in SHHS because the data were exported from versions of the scoring software more than 20 years ago. That software no longer works and we have backwards compatibility issues when we try to open these data from these 1990s in modern software to try and sort out how these issues occurred. Clearly some "bad" data have made their way into the CSV/results dataset.
Sorry I couldn't be of more help. Thank you for being diligent in your review of the data and good luck with the analysis!
