Final version published! http://www.sleep-journal.com/article/S1389-9457(17)30212-5/pdf
Understood, thanks Mike!
I was just informed that the uneditted version is out: http://www.sciencedirect.com.ezproxy.lib.monash.edu.au/science/article/pii/S1389945717302125
I will let you know again when the full version is ready.
Thanks Mike, let me know when you know.
@Eptehal: It's about the relationship between obesity and excessive daytime sleepiness. What is yours?
Our (SHHS) article has been accepted for publication, thank you very much for your help!
Do you know if I need to have open access for this article? Since it's funded by NIH and NIH requires its articles to be deposited to PMC?
Many thanks =)
The mop file is very useful, thank you. I think I now understand what the filtering is for. Some notes below for others to check!
**Arousals in REM unreliable: when EMG is artifactual or absent during all or REM portion of the study.
Respiratory events/RDI unreliable: when due to the technical quality of the respiratory signals,
distinctions between hypopneas and normal breaths are equivocal in over 20 % of scored events ; also when the quality of the oximetry signal raises doubts about actual magnitude of desaturation linked with over 20 % of respiratory events (unstable baseline).
Apnea/hypopnea unreliable – when airflow signal is artifactual or absent for over 20 % of scored respiratory events.**
I am not sure which variables were used for filtering; but it seems like this filter "airqual >2" was used for OAHI
Thanks again Mike! Now I can address the reviewer's comments!
Thanks for clarifying. The only difference between oahi and ahi_a0h4 seems to be the filtering, and it makes sense to me to include the filtering.
Do you know if there's a similar RDI/AHI variable with the filtering applied?
Also, how was the apnea defined? I think current guideline is at least 90% reduction of airflow for 10s...
But not sure about the shhs dataset. Is it "airflow drop to 25% of baseline, for at least 10s"?
Hi again Mrueschman
I wonder why for oahi at baseline, n is equal to 5,106; but for ahi_a0h4 at baseline, n is equal to 5,804?
Shouldn't they have the same "n"?
Sorry to trouble you!
Thanks Mrueschman and Dan, much appreciated!
