PFS, OS, TTUP, Estimated using the Kaplan-Meier method to calculate the median survival time and 95% confidence interval.
ORR, DCR, Calculated based on RECIST or mRECIST criteria; rates are presented along with 95% confidence intervals.
Between-group comparisons (baseline and stratified analyses): The Mann-Whitney U test is used for between-group comparisons of continuous variables.
For comparisons of categorical variables, the X^2 test or Fisher's exact test will be used.
To identify factors influencing PFS, OS, and TTUP, univariate and multivariate analyses using the Cox proportional hazards model will be performed.
Multivariate analyses will include factors considered clinically important, as well as those showing statistical significance or a trend (e.g., P<0.1) in the univariate analysis.
