Neck Grasp Predicts Obstructive Sleep Apnea in Type 2 Diabetes Mellitus

Table 3

Comparison of Linear regression (c-statistic) for ESAP, BMI, neck circumference, and gap measure.

Screening Test	Area under the curve
ESAP	0.657
BMI (continuous)	0.705
Neck Circumference (cm)	0.885
Gap Measure (cm)	0.724

measure was the number of cm between the fingers in a patient with a positive ESAP. STOP-Bang and BQ were not included because they were scored dichotomously.
