NK cell infiltration is associated with a decreased risk of dying in patients with solid tumors. (A) A random effects model meta-analysis was conducted on the 30 studies revealing a decreased risk of death in patients with greater NK cell infiltration (HR=0.34, 95% CI: 0.26–0.46; p<0.0001). Forest plots demonstrate pooled meta-analysis results by solid tumor type and pooled meta-analysis results from all solid tumor types. (B) All studies which reported HR values were visualized by Forest plot, grouped by tumor type (dots indicate the size of patient population studied).
