The Immunity-risk model. To construct the Immunity-risk model, two steps (prognostic immune cells screening and model establishing) were conducted. Prognostic immune cells screening: 4 prognostic immune cells were finally enrolled into the Immunity-risk model after univariate Cox regression analyses, Lasso regression analyses and both backward and forward stepwises selection based on the AIC. Immunity-risk model establishing: The final immune model was constructed by multivariate Cox regression analyses and generated a immunity risk score for every patient. The forest plots of 22 immune cells in univariate Cox regression analyses. The first column was the name of 22 immune cells; the second column showed the P value; the third column illuminated the HR and 95%CI of 20 pathways; the forth column was the forest plots of HR and 95%CI
