HP and hepatocellular carcinoma: Saliva ORM1 levels in the HCC group were significantly higher than in the non-HCC group (p < 0.001) (Fig. 3b). Saliva HP expression in the HCC group was significantly higher than in the LC and NC groups (p < 0.001), but there was no statistically difference in salivary HP between the HCC and CHB groups (p = 0.219) (Fig. 3c).
