Statistics
Continuous variables are presented as mean +/- standard deviation or
median. Categorical data are expressed as frequencies and percentages.
Univariate comparisons were performed using t-test (continuous
variables) and the X²-Test. A p-value of <0.05 was considered
statistically significant. Cumulative event rates were calculated using
the Kaplan-Meier method. A log-rank test was performed to compare event
distribution between both groups. All analysis were performed using SPSS
for Mac version 27.0 (SPSS Inc., Chicago, IL, USA).
