Values are presented as mean ± standard deviation or number (percentage). Continuous variables were compared using the independent-samples t-test or Welch’s t-test, as appropriate. Categorical variables were compared using the Pearson chi-square test or Fisher’s exact test, as appropriate. The p-value for surgical procedure category represents the overall comparison across all categories. Abbreviations: ASA American Society of Anesthesiologists, BMI body mass index, min minutes
