Abundance of Fusobacterium spp. and F. nucleatum in gastric cancer patients. (A) Proportion of Fusobacterium spp. positivity in non-tumorous (N-GC, n = 78) and tumorous gastric cancer tissues (T-GC, n = 81). (B) Proportion of F. nucleatum positivity in N-GC (n = 78) and T-GC (n = 80). (C) Correlation between Fusobacterium spp. and F. nucleatum in N-GC and T-GC. (D) Correlation of Fusobacterium spp. abundance between N-GC and T-GC. (E) Correlation of F. nucleatum abundance between N-GC and T-GC. Data are presented as raw Ct-values; negative undetectable values were set to Ct of 40, CT-value > 38 were defined as negative and CT-value ≤ 38 were defined as positive. Fisher’s exact and Spearman’s tests were used for analyses.
