COX5B and neoplasm: Comparisons of the COX5B and CLDN2 T/N ratios between subgroups with COX5B T/N < 1 and ≥ 1 are shown in Figure 5B. Further correlation of COX5B and CLDN2 staining intensities using Pearson correlation analysis revealed no correlation in the non-tumor sections (Figure 5C, r = 0.045, p = 0.692), but marked correlations in the tumor sections (Figure 5D, r = 0.557, p < 0.001).
