Brief Summary

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

The purpose of the Swedish Obese Subjects (SOS) study is to examine the long-term effects of bariatric surgery on overall mortality and obesity-related co-morbidities.

Detailed Description

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

The Swedish Obese Subjects (SOS) study is a prospective non-randomized controlled intervention study designed to examine the long-term effects of bariatric surgery compared to usual care in obese subjects.
