Kaplan–Meier curves also revealed that except for LGG (p = 0.049), higher levels of KLRB1 expression were associated with better outcomes in ACC (p = 0.019), CESC (p = 0.009), HNSC (p = 0.002), MESO (p = 0.022), SARC (p = 0.029), SKCM (p < 0.001), THCA (p = 0.001), and UCEC (p = 0.001) (Figure 2(d)). This evidence concerns the gene KLRB1 and adrenal cortex carcinoma.
