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).
