Hi Mike,
Great, thank you!
Hi there,
1.) In SHHS annotations-events-nsrr .xml annotation files, some respiratory events are marked as "'Unsure|Unsure". I couldn't find any doc, what does that mean?
I've found the following for MrOS data: https://sleepdata.org/datasets/mros/pages/polysomnography-introduction.md
Hypopnea event tags Hypopnea events are represented by two different tags in the XML annotation files. Events with the Hypopnea tag are hypopneas with a reduction in airflow between 30% and 50% from baseline levels. Events with the Unsure tag are hypopneas with a reduction in airflow greater than 50% from baseline levels. If interested in all hypopneas that have a 30% or more reduction in airflow, both event types should be included. If interested in events with greater reduction in airflow (>50%), use those that were labeled with the Unsure tag. The Unsure tag does not represent uncertainty about the event, but rather was the only custom tag available in the original polysomnography scoring program.
2.) Related question: Is the format/scoring code the same for annotations-events-nsrr .xml files for different datasets from NSRR?
Best, Wolfgang
