Ovarian cancer survival by tumour grade The figure shows RRs and 95% CI for the association between ovarian cancer survival and grade for various histotypes of ovarian carcinoma, in women with ovarian cancer of known stage at diagnosis. RRs are adjusted as appropriate for age at diagnosis, year of diagnosis, deprivation, tubal ligation, hysterectomy, use of contraceptive or menopausal hormones, parity, BMI, smoking, alcohol intake, age at menarche, family history of breast cancer, frequency of strenuous exercise, and education, and stratified by region and stage at diagnosis. Note: Clear cell carcinoma and carcinosarcoma are regarded as high grade by definition, and thus are not shown here.
