In mild OSA patients, there was a negative correlation between LOX-1 and mean SaO2 during sleep (rs = −0.47; p = 0.03), although, in the whole OSA group, there were no correlations between LOX-1, neither in the sleep breathing disturbance parameters nor in the biochemical parameters (Table 2). Here, OLR1 is linked to obstructive sleep apnea syndrome.
