Thanks for the insights.
I will update the nominator by considering only hypopneas associated with a >=3% SpO2 desaturation and check if scores get closer to ahi_a0h3 values.
Hi,
I am trying to reproduce ahi_a0h3 values using the events annotation file (mesa-sleep-*-nsrr.xml). However, I am getting values way higher than the ahi_a0h3 variable values. Would it be possible to know what EventConcept tags should be used to compute the ahi_a0h3 score and what sleep duration is used as the denominator? Is it the total recording time or the total time when the subject is asleep)?
Thank you for your help!
