Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Bidirectional and causal relationship exists between obstructive sleep apnea (OSA) and hypertension in a dose-response manner, independent of confounding variables such as age, smoking, and body mass index. OSA is conventionally diagnosed and graded by apnea-hypopnea index (AHI). The relationship between AHI and changes of blood pressure deserves further investigation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Approximately 50% of patients with obstructive sleep apnea (OSA) have hypertension; up to 30% of patients with hypertension have OSA, and the prevalence is even higher in those of resistant hypertension. OSA is conventionally diagnosed and graded by apnea-hypopnea index (AHI). This retrospective study aimed to determine if OSA severity and AHI have effect on blood pressure measurements and the nocturnal changes following an overnight sleep.
