Hello, mrueschman,
I would like to know whether each subject has been monitored by polysomnography for the whole night only once, at what time and why this time was chosen. I can see which files in the dataset get this information.
Thank you.
Subjects were chosen from existing observational studies. There were two main visits/waves in SHHS, so some subjects have two overnight sleep studies collected. The first wave was between 1995-1998 and the second wave between 2001-2003.
