For categorical variables, n (%) is presented.
Patient’s height, weight and BMI are presented as the median (min; max).
Patient’s age at index surgery is presented as the mean (SD).
For comparisons between groups, Fisher’s exact test (lowest one-sided p value multiplied by 2) was used for dichotomous variables, the χ2 test was used for non-ordered categorical variables and the Mann-Whitney U test was used for continuous variables.
*Comparison between included and excluded patients.
