Habitual snoring occurring 'every night' is a significant predictor of OSA, whereas less frequent snoring is not, and daytime sleepiness (EDS) is only predictive when it manifests as dozing while driving.
Not all snoring or sleepiness indicates OSA. For snoring, it must be habitual (every night) to be a strong predictor. For daytime sleepiness, general tiredness is not predictive, but specifically dozing off while driving is a significant red flag for OSA.
GoodQualifiesHIGH confidence
With the exception of snoring, grading a 'yes' response had no additional benefit... However, in the present report, snoring was only significant if it occurred every night. A tendency to doze whilst driving proved to be the only circumstance in which EDS was more common among OSA than non-OSA patients.
Why this rating
Large sample size, clear statistical differentiation between frequency levels.

- Combining clinical features (male sex, habitual snoring, supine sleep, heartburn, driving drowsiness, alcohol, BMI, age) with overnight oximetry allows confident diagnosis or exclusion of Obstructive Sleep Apnoea (OSA) in approximately one-third of patients, thereby reducing the need for full polysomnography.Good
- In male patients, abdominal (waist) circumference is a closer independent correlate of OSA severity (AHI) than neck circumference or BMI, whereas in female patients, neck circumference is the best anthropometric correlate.Good
