Figure 4. Correlation of SFRP expression values to Stromal Scores in various cancers.

Scatterplot representations of SFRP RSEM expression values (y axes) to Stromal Scores (x axes, as determined by the ESTIMATE algorithm) in bladder cancer, breast cancer, colorectal cancer, glioblastoma, head and neck cancer, clear cell kidney cancer, lung adenocarcinoma, lung squamous cell carcinoma, ovarian cancer and endometrial cancer. Lines indicate linear regression lines; shading indicates confidence interval. Values (right) indicate average Spearman’s correlation coefficients of the individual SFRP family members in the described cancers.
