aAt least one Complication grade 3 or higher graded according to Clavien/Dindo
bMultivariate logistic regression analysis with forward stepwise including, Odds ratio (OR), 95% confidence interval (CI)
The table shows the multivariate analysis of the risk factors identified by the univariate analysis. Fluid balance on POD 0 and POD 4 were analysed in separate models to prevent multicollinearity
