Fig 1.
We screened 1,465 patients with OSAS (Apnea-Hypopnea Index≥5/h on PSG) out of 1760 patients who underwent PSG. Patients who had incomplete medical records or questionnaires, prostate disease, or bladder disease were excluded. We registered 1,264 participants, and they were divided into male and female groups and then subdivided into the nocturia and non-nocturia groups according to the following question, “Do you go to the bathroom two times or more during your sleep?”. OSAS: obstructive sleep apnea syndrome. PSG: polysomnography.
