The independent-samples t-test was used to analyze the quantitative variables. ROC curve analysis and Kaplan–Meier survival analysis were used to analyze the efficacy of R software in predicting survival outcomes (version 4.0.3). The link between a prognostic classifier and survival outcomes, as well as other clinical parameters, was investigated using a Cox proportional model. When the P-value was less than 0.05, the results were considered statistically significant.
