Supplementary Figure S3 showed the correlation between CTSB expression and immune infiltration levels in manifold cancer types. Importantly, the expression of CTSB was significantly related to at least three types infiltrating immune cells in thyroid and gynecological cancer. Furthermore, the correlation coefficients in digestive, urogenital, and respiratory cancers are presented in Figures 7A–N. This evidence concerns the gene CTSB and female reproductive organ cancer.
