BMI STOP-BANG questionnaire positively correlated measured Hypopnea Index, while ESS Berlin Questionnaire not. Positive pressure ventilation initiated 90% extremely effective median AHI falling within normal range follow up. significantly higher compared control (85% vs 66% p=013). Conclusion Older classical symptoms. STOP -BANG values other lacked validity. Treatment highly efficacious high should be considered first-line
