Continuous variables are expressed as either the median (min-max), and categorical variables are expressed as either frequency (n) and 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
