Figure 5. Prognostic and predictive analysis of COL1A2 in colon adenocarcinoma (COAD). (A) The effect of COL1A2 on DFI, DSS, OS, and PFS in COAD. The value of COL1A2 in predicting survival status of (B) DFI, (C) DSS, (D) OS, and (E) PFS. Abbreviations: DFI: disease-free interval; DSS: disease-specific survival; OS: overall survival; PFS: progression-free survival; AUC: area under the curve; 95% CI: 95% confidence interval; FPR: false-positive rate; TPR: true-positive rate.
