Body mass index was categorised as < 25, 25-29.9, and ≥ 30 kg/m², which corresponded to normal weight, overweight, and obesity, respectively. BMI: Body mass index; IQR: Interquartile range; NHANES: National Health and Nutrition Examination Surveys; OSA: Obstructive sleep apnea; TyG-BMI: Triglyceride glucose-body mass index.
