Other sleep-related breathing disorders: Participants with mixed sleep apnea, central sleep apnea, or severe snoring with an AHI index of \<5 events per hour will be excluded to ensure that the study population is limited to patients with OSAHS.
Severe internal medical conditions: Patients with severe cardiopulmonary dysfunction, malignancy, severe liver disease, mental disorders, or other severe internal medical conditions that may significantly affect sleep or the progression of kidney disease will be excluded.
Recent surgery or medication: Individuals who have undergone surgery within the past 3 months that may affect sleep or kidney function, or who are currently using medications that may significantly interfere with sleep or the assessment of kidney disease (such as corticosteroids, immunosuppressants, novel antipsychotics, etc.) will be excluded.
Pregnant women.
Inability to cooperate with the study: Patients who are unable to complete the study procedures (including polysomnography, follow-up, etc.) due to cognitive impairment, language communication difficulties, remote residence, or other reasons will be excluded.
