HeartBeat: blood, sleep, same day?

Good evening, I am checking the HeartBeat. It has two visits, baseline and followup. There is about 3 weeks between them. And both visits has edf files from sleep study, and variables from blood sample.

Are the edf files from home sleep monitoring (type II) or in sleep lab (type I)? Are the sleep study and blood sample collecting happened on the same day?

Thanks!

Does HearBEAT dataset have sleep stage annotations? I know it does not have EEG so it cannot have AASM sleep stage. But does it have binary Sleep/Awake annotated from the PSG signal such as actigraph?

Thanks for checking in. We are not sharing annotations for HeartBEAT at the moment - there's a note in the changelog here: https://sleepdata.org/datasets/heartbeat/pages/polysomnography-introduction.md

The annotations did not include a binary sleep/wake estimate based on available (non-EEG) signals.

As to your first questions, the sleep studies were all home sleep tests (Type III). The sleep studies and blood draws occurred weeks apart at baseline - the sleep study was done after consent to confirm eligibility and then the baseline visit (where the blood draw occurred) was scheduled soon after. At follow-up it's possible the blood draw would occur on the same day as the follow-up sleep study.
