Figure 3. Association between FPN1 expression and clinicopathological parameters in lung cancer patients. The relative FPN1 expression level was determined by using the UALCAN database in (A) male and female lung cancer patients, (B) lung cancer patients with stage 1 to stage 4 diseases, and (C) patients with different lymph node metastatic states (from N0 to N3 based on axillary lymph node numbers).
