All participants were assigned to the study group

1 year

This study involves a Class II, FDA-cleared medical device used within its cleared indication and standard clinical practice. The device is non-implantable, non-life-sustaining, and non-systemic, with no plausible mechanism by which its use could result in death.

Study participation does not introduce procedures or conditions associated with mortality risk. Therefore, all-cause mortality is not a relevant safety endpoint, and no participants are considered at risk.
