Clinical significance of the hemoglobin-to-red blood cell distribution width ratio in patients with severe OSAS.

ABSTRACT: This study aimed to evaluate the clinical significance of the hemoglobin-to-red blood cell distribution width ratio (HRR) in patients with severe obstructive sleep apnea syndrome (OSAS). A retrospective analysis was conducted on 216 patients who underwent polysomnography (PSG) between January 2018 and February 2023. Patients were divided into two groups according to the apnea-hypopnea index (AHI): severe OSAS (n = 131) and non-severe OSAS (n = 85). Comparisons were performed between the two groups regarding baseline characteristics, AHI, minimum blood oxygen saturation (MinSaO₂), and hematological parameters including white blood cell (WBC) count, red blood cell (RBC) count, platelet count (PLT), hemoglobin (Hb), red blood cell distribution width (RDW), hematocrit (HCT), mean corpuscular v
