Figure 4. Development of a B-cell infiltration related prognostic model. (A) A KEGG enrichment analysis of 420 genes related to B-cell infiltration and prognosis. (B–D) A LASSO Cox regression model was constructed based on B-cell infiltration-related genes to calculate the tuning parameter (λ) based on the partial likelihood deviance with tenfold cross-validation. The optimal log λ value is indicated by the vertical black line in the plot.
