Great, thanks Mrueschman, that definitely helps.
So If I want to use current definitions, the more appropriate variables would be OAHI and AHI (ahi_a0h4)?
I looked at RDI4P, it doesn't seem to include RERA.
In the dataset, OAHI was defined as
OAHI = 60 * ( hrembp4 + hrop4 + hnrbp4 + hnrop4 + oarbp + oarop + oanbp + oanop ) / slpprdp
This includes hypopneas at 4% desaturation index and apneas at any level of desaturation.
I am confused, should the apneas be at 4% as well? or was there a specific reason?
Only missed the first one. I will add it in now.
I'm about to submit my manuscript using the SHHS study dataset from NSRR.
I've cited the data source in my manuscript as:
"National Sleep Research Resource. Sleep Heart Health Study 2016 [Available from: https://sleepdata.org/datasets/shhs."
Is there any other particulars that I need to be aware of? e.g. funding source
Please let me know.
Does anyone know if there is a way to identify which parent cohort a participant is from, through the study id (pptid) in the SHHS dataset?
Great suggestion! I'll think about it.
I'm working on a sensitivity analysis for the missing data at follow-up 2 (SHHS2).
And then I found the variable 'vital' from the CVD outcomes dataset, which shows that 1,305 ppl were dead.
But at which timepoint is this? If this is not at follow-up 2, but after, is there another variable that would tell me how many people were dead at follow-up 2?
Yes that's what I was looking for. thanks!
That is a very clear explanation. Thanks Mike!
