Our results (Fig. 7) showed that among the model parameters, both the probability of KRAS mutation (αKRAS, ANOVA P-value = 0.013) and the secretion rate of EGF from cancer cells (\documentclass[12pt]{minimal}\usepackage{amsmath}\usepackage{wasysym}\usepackage{amsfonts}\usepackage{amssymb}\usepackage{amsbsy}\usepackage{upgreek}\usepackage{mathrsfs}\setlength{\oddsidemargin}{-69pt}\begin{document}}{}$R_{\mathrm{EGF}}^{\mathrm{PCC}}$\end{document}, ANOVA P-value = 0.038) were associated with Bailey subtypes (Fig. 7A). Here, EGF is linked to cancer.
