ASA – American Society of Anesthesiologists, NRS 2002 – Nutritional risk screening 2002. Continuous variables are reported as median and range. Dichotomous variables are reported as N. Continuous variables were compared using the Mann-Whitney test. Dichotomous variables were compared using Fisher’s exact test. All variables with p < 0.2 in univariate analysis were included in multivariate analysis.
