There were no significant differences in demographic and surgical data among the three groups. Numerical data were presented as numbers (percentages). Variables with a normal distribution were presented as mean ± standard deviation (SD). Variables with a skewed distribution were presented as median (quartiles). BMI: body mass index, ASA: anesthesiologists’ physical class.
