Fun Facts

"OSA is characterized by repetitive pauses in breathing during sleep."
"A score of 5 or higher is highly predictive of moderate to severe OSA."
"Early detection of OSA can reduce the risk of hypertension, stroke, and daytime accidents."
"Gender is included because OSA is historically more common in males (though frequently underdiagnosed in females)."

Formula: One point is assigned for each 'Yes' response across 8 categories (STOP and BANG).
