Looking for non-apnea subject PSG data

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.

Thank you.

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!
