Correlates of vascular dimensions in patients with OSA. (A) The diameter of AA was negatively correlated with SpO2mean (B = − 0.168, P = 0.037); (B) The diameter of DTA was negatively correlated with TST (B = − 0.170, P = 0.034); (C) The diameter of MPA was negatively correlated with SpO2mean (B = − 0.167, P = 0.037).
