Statistical analyses
Patient characteristics and results are reported as means ± standard deviations for normally distributed quantitative data or as medians and interquartile ranges for non-normally distributed data. Nominal and categorical variables are expressed as numbers (percentages). The primary outcomes were post-operative complications (yes/no) and POF (yes/no). A Chi-square test was used for dichotomous variables and a Student’s t-test was used for continuous variables. Multivariate binary logistic regression was used to evaluate independent association between patient characteristics and the development of complications or POF as a dichotomous variable.
All statistical analyses were performed using IBM SPSS Statistics, version 25. Results were considered statistically significant at p < 0.05.
