Figure 3. The trend of BMI score increase over time (6 weeks prior to surgery up to 12 months after surgery) is presented in both groups. In both groups, there were no statistically significant changes in BMI (p> 0.05) over time. 6wBS–6 weeks before surgery, JBS–just before surgery, AS–after surgery, 3mAS–3 months after surgery, 6mAS – 6 months after surgery, 12mAS–12 months after surgery.
