When analyzing survival probability differentially in liver cancer and CRC, a significant association was only found between NRP1 overexpression and lower survival in liver cancer patients (HR 1.62, 95% CI 1.18–2.21, p < 0.001), not observing this association in CRC patients (HR 1.22, 95% CI 0.96–1.54, p = 0.11) (Figure 2b). Here, NRP1 is linked to liver cancer.
