Many studies have identified a relationship between OSA and motor vehicle accidents. Patients with OSA have been reported to be 2-7 times as likely as control individuals to have a motor vehicle crash; the overall estimated risk was 2.5 in a meta-analysis of 6 studies. [58] Many studies indicate that motor vehicle accidents are more common in patients with severe OSA (generally, AHI >30), [59, 60] but this is not a universal finding. [61]
