LASSO Cox regression analysis of immune-related genes in HCC. a The solution path plot of each independent variate. The lateral axis and longitudinal axis represent the lambda value and independent variable coefficient, respectively. Each curve corresponds to a variable. b The confidence interval for each lambda, including the cross-validation curve (red dotted line) and upper and lower standard deviation curves along the λ sequence (error bars). The selected λ is shown by the vertical dotted lines. LASSO, least absolute shrinkage and selection operator. c Analysis of the prognostic value of the selected LASSO cox hub genes and ImmuneRiskScore
