I have a question about the stucture of the polysomnography of the BestAIR dataset. It should have 3 visits. while the subfolder names are "baseline", "followup" and "nonrandomized". Are these three folders corresponds to different visits? If not, how to get PSG data for each visit?
Thanks for using the site. The followup folder should contain home sleep test data from both 6-month and 12-month "final visits" (https://sleepdata.org/datasets/bestair/variables/final_visit). Subjects should only have one or the other (i.e., none with both 6-month and 12-month), or follow-up should be missing entirely.
The nonrandomized folder contains subjects who were screened with home sleep testing but were either 1) found to be ineligible or 2) opted not to continue to randomization. The baseline and followup folders contain data from randomized subjects.
Thanks a lot for the explanation. It is very helpful.
