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.
