Statistical Analysis
All data were summarized with standard descriptive statistics. Overall survival (OS) and corresponding 95% confidence intervals (CI) were calculated and presented using the Kaplan-Meier method. Comparison of survival curves was performed using Log-rank (Mantel-Cox) tests. P-values <0.05 were considered statistically significant. Statistical analyses were calculated and graphics designed using Prism 9 software (GraphPad, La Jolla, CA, USA).
