CD4 and lung adenocarcinoma: Third, to evaluate the impact of immune infiltration and ALDOA on the survival differences of lung adenocarcinoma patients, we used TIMER to draw Kaplan-Meier plots for immune infiltration and ALDOA. The results in Figure 11C showed that low levels of B cells, CD4+ T cells, macrophages, neutrophils, and dendritic cells were associated with poor prognosis of lung adenocarcinoma patients.
