In the SHHS data, are there subjects who were identified as "healthy" or "control" without any sleep disorders? What is the best way to screen for this subset of data? I have tried searching for AHI<5, for example, but have not seen what I need.
We didn't create healthy subject indicators, but you could use a variable like ahi_a0h3 to create a categorical variable (e.g. AHI<5 vs. AHI >=5).
The Medical History variables are also commonly used when grouping subjects by health status. Same for the CVD Outcomes variables.
Let me know if I can help further. Thanks for checking out the NSRR!
