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).
