Figure 6 Hematoxylin-eosin and immunohistochemical staining of FOLH1 in 60 additional gastric intestinal metaplasia patients. A: Positive staining of FOLH1 (brown color) was significantly higher in the epithelium of [non-progression group (N)] N1-intestinal metaplasia (IM), compared to progression group (P group) P1-IM; B: Integrated optical density (IOD) of FOLH1 expression in different groups: N1-IM, N2-IM, P1-IM, and P2-IM; C: The diagnostic cutoff value for FOLH1 is 0.302, a sensitivity of 1.0, and a specificity of 0.967, respectively. The corresponding IOD value for FOLH1 is 31.46. cP < 0.001. HE: Hematoxylin-eosin; IHC: Immunohistochemical; N group: Non-progression group; P group: Progression group; IM: Intestinal metaplasia; IOD: Integrated optical density; AUC: Area under the curve.
