  1. Continuous variables are expressed as eitherβthe median (Q1: first quartile – Q3: third quartile), and categorical variables are expressed as eitherδfrequency or percentage. Continuous variables were compared with the Mann Whitney U test, and categorical variables were compared using Pearson’s Chi-Square test or Fisher exact test. Statistically significant p-values are in bold. BMI: Body mass index. ASA: American Society of Anesthesiologist; ESPB: Erector Spinae Plane Block
