Data are expressed as median (interquartile range) or n (%) unless otherwise stated. Kruskal Wallis and Χ2 (or Fisher's exact) tests were used to analyse continuous and categorical variables, respectively. PSM, propensity score matching; INR, international normalized ratio; SAPS II, simplified acute physiology score II; SID30, Elixhauser comorbidity index.
