Correlations of CA125 and HE4 in ovarian cancerous ascitic supernatant compared with serum CA125. a. Serum CA125 positively correlated with ascitic HE4 in the no chemotherapy group and the difference was significant (***p < 0.001); b. Serum CA125 positively correlated with ascitic CA125 in the no chemotherapy group and the difference was significant (***p < 0.001); c. Relationships of ascitic supernatant HE4 and serum CA125 in the different categories (***p < 0.001); d & e. The correlations of serum CA125 compared with ascitic HE4: ascitic CA125 levels did not differ significantly (p > 0.05) in the chemotherapy group; 4 f. Relationships of ascitic supernatant CA125 and serum CA125 levels among the different categories (***p < 0.001).s
