Adjusted for demographics (age, gender, and ethnicity) plus BMI, neck circumference, waist-to-hip ratio, smoking history, alcohol use
Clinically, AHI is commonly categorized using AHI cut-offs of < 5 (non-diagnostic), 5 ≥ and <15 (mild), 15 ≥ and < 30 (moderate), and ≥ 30 (severe) to indicate severity.
