CD44 was positively associated with immune cell infiltration. a Landscape of immune cell infiltration in CD44-high and CD44-low lung adenocarcinoma patients, using GSE103584 database. b The association between CD44 and infiltration of immune cells (B cells, CD8 + T cells, CD4 + T cells, macrophage, neutrophil, dendritic cells) using Tumor Immune Estimation Resource (TIMER). c The association between CD44 copy number variation (deep deletion, arm-level deletion, diploid/normal, arm-level gain, high amplification) and the infiltration of immune cells (B cell, CD8 + T cell, CD4 + T cells, macrophage, neutrophil, dendritic cells) was analyzed. ***: < 0.001, **: 0.001 ≤ ** < 0.01, *: 0.01 ≤ * < 0.05
