Compared to the PTLS‐ group, higher expression of FUT4 in the PTS+ group in paracancer (PTLS− vs. PTLS+, 12.62, 30.03, p < 0.001), and the two groups in cancer (PTLS− vs. PTLS+, 23.28, 26.24, p = 0.54) were not statistically significant (Figure 3C). The gene discussed is FUT4; the disease is cancer.
