Fig. 5. Frequency of CXCL9 overexpression is higher in clear-cell carcinomas than in other histological subtypes of ovarian cancer.

a Representative pictures of immunohistochemical CXCL9 staining patterns in different ovarian cancer subtypes. Intensity scores +1 and +2 were summarised as “low” expression group, whereas score +3 was stated as “high” expression group (scale bar 50 µm). b Relative distribution of low and high CXCL9-expressing samples within each histological subtype.
