Comparison of Intracranial and Extracranial Carotid Artery Calcifications between Obstructive Sleep Apnea Patients and Healthy Individuals: A Combined Cone-Beam Computed Tomography and Polysomnographic Study

Table 5

Multiple linear regression on the apnea-hypopnea index (AHI) coefficients and their 95% confidence intervals (95% CI) was used to assess the associations to the calcifications with adjustment for sex, body mass index (BMI) neck circumference, and age in OSA patients.
