"The Central Denmark Region Committees on Biomedical Research Ethics approved the study (ID: 1-10-72-363-15). The study was registered at ClinicalTrials.gov (NCT02713555) and at the Danish Data Protecting Agency and was conducted in accordance with the Declaration of Helsinki. Conclusion: Our data suggest that RYGB and SG improve basal fuel metabolism and two-step insulin sensitivity in the liver, muscle, and fat and seem equally favourable when investigated 2 months after surgery. This trial is registered with NCT02713555."
