NCAM1 and fibrosis: While the percentage of cytotoxic CD56+CD16+ NK cells was higher in patients with advanced fibrosis though not statistically significant (84.5 ± 11.8 vs. 81 ± 15.8, p = 0.29), the percentage of immature cytokine-secreting CD56+CD16− NK cell was significantly lower in patients with advanced fibrosis (5.1 ± 3.4 vs. 7.6 ± 6.2, p = 0.03).
