Question Title

* In the study "Belun Ring (Belun Sleep System BLS-100): Deep learning-facilitated wearable enables obstructive sleep apnea detection, apnea severity categorization, and sleep stage classification in patients suspected of obstructive sleep apnea," how did the Belun ring perform relative to in-lab PSG in detecting OSA, as reported in the article?

It was only able to detect OSA in healthy individuals

It showed good accuracy and moderate-to-substantial agreement for OSA severity and sleep staging

It consistently underestimated AHI by half

It had poor agreement and could not detect OSA

Question Title
