Based on the colorectal cancer dataset GSE19860, Spearman’s method was used to analyze the correlation between SERPINA1 and FOXA1 (r = 0.19, P = 0.23) (Fig. 6C) and the correlation between SERPINA1 and CEBPB (r = 0.45, P = 0.0034) (Fig. 6D). This evidence concerns the gene SERPINA1 and colorectal cancer.
