The distinct roles of OSA and depression severity in day- and night-time symptomatology in OSA patients: a pilot study

Purpose Obstructive sleep apnoea (OSA) is a common sleep disorder and is associated with a number of comorbid conditions, including the frequent occurrence of depression. Notably, there is a considerate overlap in day- as well as night-time symptomatology in depression and OSA. In light of this, we aimed to disentangle the distinct effects of OSA and depression severity on day- and night-time symptomatology.
