Cox regression analysis of OS identified that HAVCR2 was markedly correlated with the prognosis of glioma (GBMLGG) (p < 0.001), KIRC (p = 0.01), LGG (p = 0.001), osteosarcoma (p = 0.004), SKCM (p < 0.001), and uveal melanoma (UVM) (p = 0.002) (Figure 1D). This evidence concerns the gene HAVCR2 and uveal melanoma.
