All categorical data are presented as numbers (percent). Age, BMI, and Charlson comorbidity index are expressed as mean ± standard error. The Kruskal–Wallis-Multiple comparison Z-value test (Dunn’s test) tested the difference between groups (age, BMI, Charlson comorbidity index), and similar symbol (Asterisk *) indicates statistical significance between groups. Pearson’s chi-squared test was used for categorical data. Abbreviations: BMI, body mass index; N, number of subjects.
