Statistics
Binary and categorical variables were analyzed by calculating
proportions, while continuous variables were assessed by calculating
median and range. Missing data or irrelevant responses were excluded
from the P value calculations. Fisher’s exact test and χ² test were
employed for categorical variables, while t-tests were utilized for
continuous variables. Significance was determined at a P value
<0.05. Survival analyses were presented using Kaplan-Meier
curves. All calculations were performed using STATA software (v. 17.0).
