Chi-square analysis was used for assessing demographic variables with two groups by surgery type. Fisher’s exact test was used for cell sizes <5. Mann–Whitney U test was used for examining the relationship of nonparametric continuous variables by surgery type (age, height, weight, %TWL, BMI, ΔBMI, EBW, %EWL, BAI, and BDI). Significant at <0.05 level.
