💬In plain words
What the trial is, and whether it could suit you
Obstructive sleep apnea (OSA) is highly prevalent in chronic kidney disease (CKD) patients and strongly linked to obesity, metabolic syndrome, and type 2 diabetes. Besides elevating cardiovascular disease risk, OSA may worsen renal function and diminish quality of life, making its understanding critical for CKD patient health.
This study will establish a large, long-term cohort of non-dialysis CKD patients to identify OSA risk factors, explore OSA's association with adverse renal outcomes, and determine OSA prevalence and epidemiological characteristics within the CKD population. The findings will provide a scientific foundation for early OSA identification, diagnosis, and intervention in CKD patients.
