Clinical significance of nerve growth factor and tropomyosin-receptor-kinase signaling pathway in intrahepatic cholangiocarcinoma

Figure 2 Correlations between overall survival rate and detected proteins. Expressions of NGF (A) and TrkA (B) have no significant association with prognosis of IHCC (P = 0.201 and 0.483, respectively). The group with NGF and TrkA double higher expression had poorer prognosis than the non-NGF/TrkA double higher group (C) (including both lower expression, only NGF higher and only TrkA higher, P = 0.003). NGF: Nerve growth factor; IHCC: Intrahepatic cholangiocarcinoma; TrkA: Tropomyosin-receptor-kinase.
