Standard Care
Both groups received routine information, including general information on diet and post-operative physical activity, as a part of standard care. They all had pre-operative visits and post-operative visits at 6 weeks and 12 months after surgery. The control group did not receive any intervention or additional information on for example benefits of physical activity, medications, or vitamins, other than that routinely included in standard care. While weight is assessed at every post-operative visit, post-surgery physical activity is not evaluated in a standardized manner within standard care.
