Prediction equations for the presence or absence of OSA (AHI ⩾5)*
| Variable | OSA | Normal | |
|---|---|---|---|
| *A patient’s score is calculated for both equations by multiplying the raw score for each coefficient and summing these products. The larger score indicates the group to which the patient more likely belongs. | |||
