Fig. 2. Overall survival of patients according to obesity and surgeon experience. Although the difference was not statistically significant, the overall survival rate tended to be lower in patients with high visceral fat area (VFA) in the 'before learning curve' group. BMI = body mass index; BMI-H = BMI ≥25 kg/m2; VFA-L = VFA<100 cm2; VFA-H = VFA≥100 cm2.
