Figure 4. Prognostic value of FPN1 in lung cancer. (A–C) The correlation between FPN1 expression and OS, FP, and PPS in lung cancer patients based on Kaplan-Meier plotter. (D–F) In the PrognoScan database, the GSE17710, GSE8894 and GSE31210 cohorts were utilized to investigate the correlation between FPN1 expression and OS and RFS in lung cancer patients. (G, H) A forest plot was generated to show the connection between FPN1 expression and the clinicopathological features of LUAD and LUSC patients.
