In contrast, VCAM-1 was not significantly associated with cardiovascular events in the whole cohort (OR = 1.44, 95% CI 0.68–3.04, p = 0.34) nor in patients with OSA (OR = 1.23, 95% CI 0.55–2.73, p-value for interaction = 0.28). This evidence concerns the gene VCAM1 and obstructive sleep apnea syndrome.
