Figure 4: Survival curves from the propensity score matching analysis. The graphs show survival in each category based on BMI and stratified by postoperative BMI change categories. MO: morbidly obese, OB = obese; OW = overweight; UW = underweight; losers: ≥5% BMI decrease; gainers: ≥5% BMI increase; no change: <5% BMI increase or decrease
